Metasurface elements, integrated systems incorporating such metasurface elements with light sources and/or detectors, and methods of the manufacture and operation of such optical arrangements and integrated systems are provided. Systems and methods for integrating transmissive metasurfaces with other semiconductor devices or additional metasurface elements, and more particularly to the integration of such metasurfaces with substrates, illumination sources and sensors are also provided. The metasurface elements provided may be used to shape output light from an illumination source or collect light reflected from a scene to form two unique patterns using the polarization of light. In such embodiments, shaped-emission and collection may be combined into a single co-designed probing and sensing optical system.

A tool for a plug to which a cable having its basal end covered with a boot is attached is disclosed. The plug includes a plug body fitted to an adapter and a slider supported on the plug body. The tool includes an insertion portion that catches the slider, and a boot surrounding part that has a sleeve-like shape and accepts insertion of the cable and the boot, to accommodate the boot while the insertion portion is catching the slider. The boot surrounding part includes a slit extending along an entire length in an axial direction of the boot surrounding part and having a width greater than a diameter of the cable and smaller than a maximum diameter of the boot. While the insertion portion is catching the slider, the boot surrounding part is positioned inner than an outermost shape line of the plug as seen in the axial direction.

An illumination system for a medical technology therapy and/or diagnosis system is provided. The system includes a light source, an optical waveguide, and an optical element in the form of a diffuser element. The optical waveguide has a first end that is connectable or assignable to the light source and the diffuser element is arranged at a second end of the optical waveguide so that light from the optical waveguide is injected into the optical element. The optical element has a lateral surface covered by a reflector layer at least in a section thereof. The reflector layer includes a mirror layer. The optical element has a light-reflecting area covered by the reflector layer and a light-transmissive area that is free of the reflector layer. Thus, light injected into the optical element is reflected on the light-reflecting area and emitted from the light-transmissive area.

The box has a base (10) and a (20) which is hinged to the base (10 and displaceable between a closed position and an open position. At least one peripheral wall (12) of the base (10) is provided with at least two lateral openings (13) each being flanked by two inclined recesses (13a/13b) and each closed by a sealing grommet (30) for the passage of at least one multi-fiber optical cable (CO) and which is pressed into the lateral opening (13) to receive thereon a sealing gasket (24) carried by the lid (20). A splitter accommodation tray (60) has a front face (61) attached to the top wall (21) of the lid (20) and carrying splitter and/or fiber accommodation means (MSF), and a rear face (62) covered by a splitter protective plate (PS). Each splitter and/or fiber accommodation means (MSF) is connectable to a fiber extension (EF1) of an optical cable (CO) received in the base (10) and to fiber extensions (EF2) connected to output adapters (AS) mounted. on at least one peripheral wall (22) of the lid (20) and externally connected to connectors (C) of terminal cables (CT).

A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.

Aspects of the present disclosure describe improved supercontinuum generation based upon alternating optical dispersion along a waveguide length that advantageously generates much more spectral bandwidth than possible with conventional, prior art techniques without losing coherence as well as supporting a larger range of pulse energies (i.e., for lower than conventionally allowed pulse energies or high pulse energies).

A first optical waveguide layer and a second optical waveguide layer are optically connected by a resin optical waveguide composed of a resin core composed of a light-transmitting resin and a cladding composed of air surrounding the resin core. A hollow outer wall structure that houses the resin optical waveguide is provided. An enclosed space is provided inside the outer wall structure. The outer wall structure is disposed to bridge the gap between the first optical device and the second optical device.
