Light wave multiplexer/demultiplexer device has parallel demultiplexing light conductors and at least 2 multiplexing light conductors

摘要

The device (1) has a single-stage optical multiplexer/demultiplexer (2), the supplied light signals combined or divided on one side, with parallel demultiplexing light conductors (4) connected to the demultiplexing side (6) and at least 2 multiplexing light conductors (10,12) connected to the multiplexing side (14). Each multiplexing light conductor is exclusively associated with a group of demultiplexing light conductors. Also included are Independent claims for the following: (a) a method for bidirectional multiplexing/demultiplexing of light signals; (b) a method for unidirectional demultiplexing of light signals; (c) a method for unidirectional multiplexing of light signals
