TLDR
In this article, a single modulator modulates the output of an array of individually actuable semiconductor lasers integrated onto the same substrate as the modulator, and an optical combiner is used to combine the outputs of the lasers.Abstract:
A wavelength-division-multiplexed transmitter has a single modulator modulating the output of an array of individually actuable semiconductor lasers integrated onto the same substrate as the modulator. An optical combiner integrated onto the same substrate between each of the lasers and the single modulator combines the outputs of the lasers. One or more of the lasers are activated as desired for wavelength division multiplexing.read more
