DETAILED DESCRIPTION OF THE INVENTION

(12) Referring now specifically to FIG. 4, one representation of the invention is an apparatus [A], [B] comprising a source of UV photons [1], one or more stand alone angular momentum generators [2] configured to deliver UV photons with optimized spin angular momentum (SAM), org orbital angular momentum (OAM), and/or a SAM/OAM [3] combination to target organic or inorganic substance and/or impurity. The angular momentum generator can have different forms [a], [b], [c], and [d].

(13) Referring now specifically to FIG. 4 [2a], UV photons can acquire optimized OAM with a Spiral Phase Plate made of UV transparent material with refractive index n, having an inhomogeneous thickness, h proportional to the azimuthal angle

(14) $h=h_s\frac{}{2}+h_0$
where h.sub.s is the step height, and h.sub.0 is the base height. When a beam of electromagnetic radiation (Gaussian) with plane phase distribution passes through this OAM generator, an optical vortex charge q is imprinted according to

(15) $q=\frac{h_s\left(n-n_0\right)}{}$

(16) This means that the output beam of electromagnetic radiation will carry OAM per photon equal to q, where is the Reduced Planck's constant. For a given electromagnetic wavelength in the UV range of the electromagnetic spectrum, then the vortex charge q can be engineered by controlling the optical step h.sub.s.

(17) Referring now specifically to FIG. 4 [2b], UV photons can acquire optimized OAM by passing flux of electromagnetic radiation having incident circular Lauerre-Gaussian through a computer generated diffraction grating with groove bifurcation known as fork holograms, pitchfork holograms, or fork-like holograms. If as single groove divides into +1 branches then the n-order diffracted beam of electromagnetic radiation acquires the optical vortex (photons carrying OAM) with topological charge
l=n

(18) [2b] shows fork hologram with a single groove that divides into 1 branch, therefore =1. For a given electromagnetic wavelength in the UV range of the electromagnetic spectrum, then the topological vortex charge l can be engineered by controlling the number of branches. For operation for a given electromagnetic wavelength in the UV range, the diffraction grating needs to be fabricated with features equal of smaller than said wavelength .

(19) Computer generated holograms that function as angular momentum generators can be designed and fabricated as phase filters that also exhibit super-resolving capabilities. Super-resolution diffracting elements are designed numerally by modifying a pattern of concentric rings similar to those illustrated in [2c]. Super-resolved Phase filters that function as angular momentum generators can be based on the so-called use a design methods based on the so-called Prior Discrete Fourier Transformation (PDFT). For operation for a given electromagnetic wavelength in the UV range, concentric ring patterns, and PDFT patterns must be fabricated with features equal of smaller than said wavelength .

(20) [2c] shows a Q-plate used as SAM/OAM angular momentum generator. Similarly to a Spiral Phase Plate [2a], a Q-plate influences electromagnetic radiation by making it interact with matter that is both optically inhomogeneous and anisotropic. The design of a Q-plate can be implemented dynamically using liquid crystals, and polymers, or subwavelength gratings. For operation for a given electromagnetic wavelength in the UV range, the patterns created with liquid crystals or polymers, and the features of the gratings must be equal of smaller than said wavelength .

(21) [2d] shows a thin single domain magnetic needle approximating a magnetic monopole used to generate an optical vortex (OAM carrying photons) angular momentum generator. A beam of electromagnetic radiation is passed through a through a round aperture upon which a thin-tip magnetic rod is secured. OAM tuning is controlled by the magnetization of the single domain magnetic needle.

(22) Referring now specifically to FIG. 5, one representation of the invention is an apparatus [A], [B], and [C] comprising a source of UV photons such as, but not limited to a UV Laser, a UV Light Emitting Diode, or a UV emitting plasma discharge lamps [1], one or more stand alone angular momentum generators [2] configured to deliver UV photons with optimized spin angular momentum (SAM), org orbital angular momentum (OAM), and/or a SAM/OAM [3] combination to target organic or inorganic substance and/or impurity. In this particular incarnation, the idea is to have a design for an optimized angular generator such as a Spiral Phase Plate, a hologram, a Q-plate, or a single domain magnetic needle approximating a magnetic monopole that can be fabricated and scaled using Very large Scale Integration (VLSI) fabrication techniques so that the device can be fabricatedas an array or notonto the surface of a freestanding UV transparent medium, FIG. 5 [A][2], or onto the surface of a UV transparent window (an aperture) such as the UV transparent window of a packaged UV Laser Diode, FIG. 5 [B][2]. Since hologram features must be equal or smaller then the UV wavelength (400 nm or smaller), then VLSI fabrication techniques can be used to integrate an optimized angular generator such as a Spiral Phase Plate, a hologram, a Q-plate, or a single domain magnetic needle approximating a magnetic monopole onto the surface of a solid state die (Laser Diode, Light Emitting Diode, Microplasma Discharge Bulb as shown in FIG. 5 [C][2].

(23) Referring now specifically to FIG. 6, one representation of the invention is an apparatus comprising a source of UV photons such as, but not limited to a UV Laser, a UV Light Emitting Diode, or a UV emitting plasma discharge lamps [1], an angular momentum generator that is also a PDFT phase filter that exhibits super-resolving capabilities [2] configured to deliver a super-resolved beam of UV photons with optimized spin angular momentum (SAM), org orbital angular momentum (OAM), and/or a SAM/OAM combination [3] that can be efficiently coupled to fiber optics [4] to target organic or inorganic substance and/or impurity. In this particular incarnation PDFT patterns must be fabricated with features equal of smaller than said wavelength .

(24) Referring specifically to FIG. 7, one representation of the invention is an apparatus comprising a source of UV photons such as, but not limited to a UV Laser, a UV Light Emitting Diode, or a UV emitting plasma discharge lamps [1], an angular momentum generator that is also a PDFT phase filter that exhibits super-resolving capabilities [2] configured to deliver a super-resolved beam of UV photons with optimized spin angular momentum (SAM), org orbital angular momentum (OAM), and/or a SAM/OAM combination [3] that can be efficiently coupled to fiber optics [4] to target organic or inorganic substance and/or impurity. In this particular incarnation, the idea is to have a design for an angular momentum generator that is also a PDFT phase filter that exhibits super-resolving capabilities that can be fabricated and scaled using Very large Scale Integration (VLSI) fabrication techniques so that the device can be fabricatedas an array or notonto the surface of a freestanding UV transparent medium, FIG. 7 [A] [2], or onto the surface of a UV transparent window (an aperture) such as the UV transparent window of a packaged UV Laser Diode, FIG. 7 [B][2]. Since the features of the momentum generator/PDFT super resolving phase filter must be equal or smaller then the UV wavelength (400 nm or smaller), then VLSI fabrication techniques can be used to integrate it onto the surface of a solid state die (Laser Diode, Light Emitting Diode, Microplasma Discharge Bulb as shown in FIG. 8 [C][2].

(25) Referring now specifically to FIG. 8, one representation of the enhanced damage to nucleic acid with germicidal UV photons carrying optimized spin angular momentum (SAM) [C], and/or orbital angular momentum (OAM) [D]. Angular momentum transferred to nucleic acid, which is bound and not free to spin or rotate, causes torsional torque resulting in enhanced, and difficult to repair disruption and damage. In comparison, UV photos not carrying angular momentum [A] are known to cause damage to nucleic acids [B] but this kind of damage may or may not results from a chain of statistical events, and it can be repaired.

(26) Referring now specifically to FIG. 9, one representation of the conceptualized exchange of optimized spin angular momentum (SAM) [C] and/or optimized orbital angular momentum (OAM) [D] carried by UV photons that interact with matter. In this particular example, matter is represented by a UV curable polymer that results from the linking of monomers, oligomers and UV excited photo initiators. UV curable precursors [A][1], [B][1], [C][1], and [D][1] are inert until UV photons carrying sufficient energy can be absorbed by photoinitiators [B][2], [C][2], and [D][2], which will link monomers and oligomers into a chain of polymers [B][3], [C][3], and [D][3]. UV photons carrying optimized spin angular momentum (SAM) and/or optimized orbital angular momentum (OAM) will transfer their momentum to matter and so increase the probability for photoinitiators to absorb these photons [C][2], and [D][2]. This results in an enhanced polymerization [C][3], and [D][3],

(27) Referring now specifically to FIG. 10, the representation of range of operation of the invention in the UV segment of the electromagnetic spectrum: from 400 nm to 10 nm. Illustrated are also the concept of Horizontal Scalability (HS), and Vertical Scalability (VS). HS implies a general design that can be scaled to operate at different wavelength within said electromagnetic spectrum. VS implies a general design that can integrated at different system levels.

(28) One further embodiment of the invention is comprising a source of near-UV and/or UV photons, one or more stand alone angular momentum generators configured to deliver near-UV and/or UV photons with or without optimized spin angular momentum (SAM), or orbital angular momentum (OAM), and/or a combined SAM/OAM, which includes the an algorithm and/or design to achieve super-resolution with near-UV and/or UV radiation (coherent or incoherent), such as the super-resolution algorithm called Prior Discrete Fourier Transformation (PDFT).

(29) One further embodiment of the invention is comprising a source of near-UV and/or UV photons, one or more stand alone angular momentum generators configured to deliver near-UV and/or UV photons with or without optimized spin angular momentum (SAM), or orbital angular momentum (OAM), and/or a combined SAM/OAM, which includes the an algorithm and/or design to achieve super-resolution with near-UV and/or UV radiation (coherent or incoherent), such as [1] lenses designed numerically by modifying a pattern of concentric rings until the target design is obtained, [2] nonlinear design algorithms, which optimize the zone width of domains of constant phase inside the DOE aperture, either matching a finite set of signal samples, or optimizing additional components of a more complex cost function, and/or [3] super-resolution elements based on the concept of super-oscillations.

All such equivalent embodiments and examples are within the spirit and scope of the present invention, are contemplated thereby, and are intended to be covered by the following non-limiting claims for all purposes.
