OPTICAL RECEIVER MODULE USING WAVELENGTH DIVISION MULTIPLEXING TYPE

摘要

An optical receiver module includes a demultiplexer, an optical device including a right-angled mirror reflecting individual optical signals transmitted from the demultiplexer and a plurality of lenses receiving the reflected optical signals, and a plurality of photodetectors spaced apart from the plurality of lenses by a predetermined distance. The plurality of photodetectors converts the individual optical signals into electrical signals. The optical device and the demultiplexer are formed into a united structure. A distance between the lenses is equal to a distance between the photodetectors.
