    Abstract: A wavelength multiplexing optical fiber transmitter, receiver, or transceiver where multiple emitters and/or photodetectors of different center wavelengths are coupled to a single optical fiber core terminus through multiple waveguides, which may be directly printed in free space. The optical assemblies described are suitable for optical data link applications, for example, to reduce a number of optical fibers needed for a given bandwidth or increase the bandwidth of a give number of optical fibers. Bidirectional fiber termination may also be implemented with an emitter and a photodetector pair coupled to a single optical fiber core terminus through multiple waveguides.

    Abstract: A micro-LED includes a light emitter between a pair of reflective metasurfaces formed from nanostructures. The metasurfaces have different levels of reflectivity, with one metasurface reflecting nearly all light, and the other metasurface allowing some light to pass through. The reflections of the light within the micro-LED result in an improved radiation recombination rate, which results in an increased modulation speed. In addition, the light emitted from the micro-LED has a relatively narrow divergence angle and narrow emission linewidth, making the micro-LED suitable for optical communications.
