Abstract
An optical data communication system includes an optical power supply and an electro-optical chip. The optical power supply includes a laser that generates laser light at a single wavelength. A comb generator receives the light at the single wavelength and generates multiple wavelengths of continuous wave light from laser light at the single wavelength. The multiple wavelengths of continuous wave light are provided as light input to the electro-optical chip. The electro-optical chip includes at least one transmit macro that receives the multiple wavelengths of continuous wave light and that modulates one or more of the multiple wavelengths of continuous wave light to generate modulated light signals that convey digital data.
