Wavelength generator based on ring resonator photonic devices

Abstract

A device includes: a wavelength generator configured to output optical signals at a pump frequency and at first and second frequencies both different from the pump frequency, the wavelength generator including: a planar bus waveguide; a main ring resonator; a first heating element thermally coupled to the main ring resonator; an auxiliary ring resonator optically coupled to the main ring resonator; and a second heating element thermally coupled to the auxiliary ring resonator; and an electronic control module in communication with the first heating element and the second heating element, the electronic control module being programmed to control a detuning of a main ring resonance frequency from the pump signal frequency via the first heating element, and to control a spectral position of an auxiliary ring resonance frequency to produce optical signals at the first and second frequencies from the optical signal at the pump frequency.
