Injection locked multi-wavelength optical source

An optical system comprising:

• an optical transmitter configured to transmit optical signals, the optical transmitter comprising:
• a first optical source configured to emit light having different wavelengths;
• a waveguide;
• an optical coupler configured to couple the emitted light from the first optical source to the waveguide;
• and
• an array of two or more second optical sources coupled to the waveguide, each of the two or more second optical sources configured to be injection locked to a different respective wavelength of the emitted light from the first optical source, the emitted light transmitted via the waveguide coupling the first optical source to the array of two or more second optical sources;
• and
• an optical receiver configured to receive the optical signals from the optical transmitter via an optical link after different respective wavelengths of the emitted light are injected into the respective two or more second optical sources, the optical receiver comprising:
• a second waveguide;
• an array of ring resonators coupled to the second waveguide and configured to be tuned to different resonant wavelengths respectively corresponding to different wavelengths of the emitted light from the first optical source;
• and
• an array of photodetectors, each photodetector coupled to a respective ring resonator of the array of ring resonators.
