摘要:
A system employs a flexible optical media, two connectors, and a mechanism such as a magnet that brings the connector together when the connectors are close to each other. The optical media is able to guide optical signals, and one connector is attached to an end of the optical media. Each connector also has alignment features and provides paths for the optical signals. The alignment features of each connector are shaped to mate with the alignment features of the other connector and to shift the connectors relative to each other as the mechanism pushes the connector together. The alignment features further have seated positions at which the paths in one connector are aligned with the paths in the other connector and separated by a free space gap.

A photovoltaic structure of a photovoltaic cell and a method of fabricating a photovoltaic structure, employ a nanowire having a base connected to a stub and an electrical isolation layer surrounding the stub. The stub is a constituent of a substrate surface. The nanowire extends away from the substrate surface and is wider than the stub. The nanowire base overlies a part of the isolation layer that is adjacent to the stub. A semiconductor junction comprises the nanowire. The method includes forming the stub; growing the nanowire from the stub; and conformally coating the nanowire. A nanoparticle is applied to the substrate surface. The isolation layer is created on and embedded in the substrate surface using the nanoparticle as a mask. A portion of the substrate surface underlying the nanoparticle forms the stub. The nanoparticle catalyzes nanowire growth on the stub. The stub is narrower than the nanoparticle.

A hybrid guided-mode resonance (GMR) grating, an optical filter and a method of optical filtering employ distributed Bragg reflection. The hybrid GMR grating includes a waveguide layer that supports a GMR having a GMR resonant frequency. The hybrid GMR grating further includes a diffraction grating that couples a portion of a signal incident on the hybrid GMR grating into the waveguide layer; and a distributed Bragg reflector (DBR) that reflects another portion of the incident signal. The coupled portion of the incident signal has a frequency corresponding to the GMR resonant frequency. The reflected portion has a frequency away from the GMR resonant frequency. The optical filter includes the hybrid GMR grating and a coupler. The method includes coupling an optical signal into the hybrid GMR grating and further coupling a reflected signal out of the hybrid GMR grating.

A device includes one or more waveguides and a memristive array adjacent to the waveguide(s). The memristive array is programmable to form a pattern that diffracts light and couples diffracted light into or out of the waveguide(s).

A method for fabricating a pellicle beam splitter includes etching an aperture in a support substrate; bonding a beam splitter substrate to an upper surface of the support substrate so that the beam splitter substrate covers the aperture; and depositing at least one optical coating on the beam splitter substrate. A pellicle beam splitter includes a support substrate, an aperture created in the support substrate using a semiconductor fabrication processes and a beam-splitting coating covering the aperture.
摘要:
A photovoltaic structure (100), a solar cell (100, 200) and a method (300) of fabricating a solar cell (100, 200) employ a hidden electrode (122, 222, 422) on a formed (320) mesa (120, 220, 420) and a bramble (130, 230, 430) of grown (330) nanowires. The mesa includes an insulator island (121, 221, 421) adjacent to a surface of the substrate (110, 210, 410) and the hidden electrode buried under a seed layer on the insulator island. One end of some of the nanowires (134, 234) is anchored to the seed layer (124, 224, 424) of the mesa. One end of others of the nanowires (132, 232) is anchored to a seed layer (114, 214, 414) formed (310) on the substrate adjacent to the mesa. The seed layers independently are an extrinsic semiconductor. A semiconductor junction includes the seed layers and some of the nanowires of the bramble.
