    Abstract: Bidirectional optical multiplexing employs a high contrast grating as one or both of a beam-forming lens and a relay mirror. A bidirectional optical multiplexer includes the beam-forming lens to focus light. The light is one or both of a light beam internal to and another light beam external to the bidirectional optical multiplexer. The bidirectional optical multiplexer further includes an optical filter and the relay mirror. The optical filter is to selectively pass a portion of the internal light beam at a first wavelength and to reflect portions of the internal light beam at other wavelengths. The relay mirror is to reflect the internal light beam along a zigzag propagation path between the optical filter and the relay mirror.

    Abstract: A system employs a flexible optical media (210), two connectors (220, 240), and a mechanism such as a magnet (226) that brings the connector (220, 240) together when the connectors are close to each other. The optical media (210) is able to guide optical signals, and one connector (220) is attached to an end of the optical media (210). Each connector (210, 240) also has alignment features (224, 244) and provides paths (222, 242) for the optical signals. The alignment features (224) of each connector are shaped to mate with the alignment features (244) of the other connector and to shift the connectors (220, 240) relative to each other as the mechanism (226) pushes the connector (220, 240) together. The alignment features (224, 244) further have seated positions at which the paths (222) in one connector are aligned with the paths (242) in the other connector and separated by a free space gap (230).

    Abstract: 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.
