WAVELENGTH MULTIPLEXING DEVICE

摘要

PURPOSE: To provide an output of an output light as a wavelength multiplex signal from one output port by selecting optionally P-sets of light sources among N sets of light sources with different wavelength. CONSTITUTION: A conversion matrix 18 uses input ports to selectively receive light sources with an optional wavelength among N sets of light sources 1,...N with different wavelength and uses a photocoupler 20 to repeat wave synthesis and provides finally the resulting output light from an output port 28 as a wavelength multiplex signal.
