A composite all optical-fibre based tapered photonic waveguide (110) including a single or multiple secondary waveguides (120) within or around a primary waveguide (118) is described. The composite optical fibre may also be termed a beam tailoring optical fibre (BT Fibre) (110). In use, at thelarger secondary end (114) both the primary waveguide (118) and the secondary waveguide/s (120) may guide modes at a particular wavelength. However, at the same wavelength, adiabatically tapering down the waveguides (118, 120) reduces the dimensions of the secondary waveguide/s (120) such that all the secondary waveguide/s (120) become effectively non-guiding at the smaller primary end (112), whilst the primary waveguide (118) still guides. In other words, the composite optical fibre is a spatially modulating optical fibre (110).

Disclosed are transparent energy relay waveguide systems for the superimposition of holographic opacity modulation states for holographic, light field, virtual, augmented and mixed reality applications. The light field system may comprise one or more energy waveguide relay systems with one or more energy modulation elements, each energy modulation element configured to modulate energy passing therethrough, whereby the energy passing therethrough may be directed according to 4D plenoptic functions or inverses thereof.

The present disclosure relates to limitation of noise on light detectors using an aperture. One example implementation includes a system. The system includes a lens that focuses light from a scene toward a focal plane. The system also includes an aperture defined within an opaque material. The system also includes a plurality of waveguides. A given waveguide of the plurality has an input end that receives a portion of light transmitted through the aperture, and guides the received portion toward an output end of the given waveguide. A cross-sectional area of the guided portion at the output end is greater than a cross-sectional area of the received portion at the input end. The system also includes an array of light detectors that detects the guided light transmitted through the output end.

An optical mouse operated with respect to an illuminated surface outside the optical mouse is provided. The optical mouse includes a light source configured to emit a light beam, and a light pipe including a first optical element and a second optical element. The light beam enters the light pipe through the first optical element, and then propagates in the light pipe from the first optical element to the second optical element without reflection, and then leaves the light pipe through the second optical element, and then illuminates the illuminated surface. The light pipe does not have any protrusion extending therefrom and attached to a front surface of the light source.

Disclosed are relay elements exhibiting transverse localization. The relay elements may include a relay element body having one or more structures, where the structures can be coupled in series, in parallel and/or in stacked configurations. The structures may have multiple surfaces such that energy waves propagating therethrough the relay elements may experience spatial magnification or de-magnification.

For forming and shifting a light intensity distribution in a focal area of an objective lens, portions of coherent input light are one by one directed into non-identical two-dimensional pupil areas of a pupil of the objective lens. Each of the portions of coherent input light is collimated in the pupil. The pupil areas include a pair of two pupil areas which are axially symmetrically arranged on opposite sides of an optical axis of the objective lens. At least one of the two discrete portions of coherent input light that are directed into the pair of pupil areas is separately modulated with regard to its phase by means of an electro optical modulator such as to form the light intensity distribution in the focal area with a local intensity minimum delimited by intensity maxima and to shift the local intensity minimum laterally with regard to the optical axis.

There is set forth herein a light energy exciter that can include one or more light sources. A light energy exciter can emit excitation light directed toward a detector surface that can support biological or chemical samples.

Disclosed are systems and methods for manufacturing energy relays for energy directing systems and Transverse Anderson Localization. Systems and methods include providing first and second component engineered structures with first and second sets of engineered properties and forming a medium using the first component engineered structure and the second component engineered structure. The forming step includes randomizing a first engineered property in a first orientation of the medium resulting in a first variability of that engineered property in that plane, and the values of the second engineered property allowing for a variation of the first engineered property in a second orientation of the medium, where the variation of the first engineered property in the second orientation is less than the variation of the first engineered property in the first orientation.

Disclosed embodiments include an energy waveguide system having an array of waveguides and an energy inhibiting element configured to substantially fill a waveguide element aperture and selectively propagate energy along some energy propagation paths through the array of waveguides. In an embodiment, such an energy waveguide system may define energy propagation paths through the array of waveguides in accordance to a 4D plenoptic system. In an embodiment, energy propagating through the energy waveguide system may comprise energy propagation for stimulation of any sensory receptor response including visual, auditory, somatosensory systems, and the waveguides may be incorporated into a holographic display or an aggregated bidirectional seamless energy surface capable of both receiving and emitting two-dimensional, light field or holographic energy through waveguiding or other 4D plenoptic functions prescribing energy convergence within a viewing volume. The waveguides may include different structures configured for each or all sensory system or energy domain to direct energy through refraction, diffraction, reflection, or other approaches of affecting the propagation paths of energy.

The photodetector includes a plurality of pixels, each pixel includes a plurality of cells, and the cell is configured to convert a received optical signal into an electrical signal. Each beam homogenization unit corresponds to at least one pixel of the photodetector, and is configured to diffuse a received incident light beam to a plurality of cells included in the corresponding at least one pixel. The optical receiving apparatus may be applied in a light detection and ranging system. The apparatus increases dynamic ranges of the detector and the light detection and ranging system, and improves detection efficiency.
