Abstract

There is disclosed in one example a communication system, including: a data transmission interface; and a wavelength division multiplexing (WDM) silicon laser source to provide modulated data on a carrier laser via the data transmission interface, the WDM laser including a single laser cavity to generate an internally multiplexed multi-wavelength laser, the single laser cavity including a filter having a first grating period to generate a first wavelength and a second grating period to generate a second wavelength, the second grating period superimposed on the first grating period.
