Abstract
A single laser multi-frequency transmitter is provided, comprising: a laser generating given modes; an optical input bus; a common optical output bus; coupling optics coupling the laser to the optical input bus; a plurality of ring resonator filters: arranged in series along the optical input bus in a one-to-one relationship with a sub-band of the given modes; optically coupled to both the optical input bus and the common optical output bus; and each configured to couple one respective frequency from the sub-band to the common optical output bus; and, a plurality of ring resonator modulators: arranged in series along the common optical output bus in a one-to-one relationship with the plurality of ring resonator filters; and each configured to modulate one given respective frequency from the sub-band so that all modes in the sub-band are modulated on the common optical output bus.
