US 2025/0147233 A1 · OPTICAL TRANSCEIVER BANDWIDTH SCALING THROUGH DIRECT OPTICAL WIRE FIBER TERMINATION

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.
