ABSTRACT:
An optical triplexer design is described in which external optical signals at a first wavelength range propagate through a laser source. The laser source provides optical signals having a second wavelength range. The triplexer features a photodetector for providing intensity feedback signals to the lasers source and a dense wavelength division multiplexer for demultiplexing the external optical.
