Abstract
A photonic, integrated circuit chip can have a frequency comb laser configured to generate a plurality of wavelengths, a plurality of modulators, one respective modulator for each wavelength of the plurality of wavelengths, the plurality of modulators being aligned in series with each of the plurality of modulators being tuned to a respective one of the wavelengths of the plurality of wavelengths, a connector configured to convey a drive signal for each modulator of the plurality of modulators, a semiconductor optical amplifier configured to receive light exiting from the plurality of modulators, and a chip having present thereon the frequency comb laser, the plurality of modulators, and the semiconductor optical amplifier. The plurality of modulators can be configured to produce a single beam of time-interleaved, multiple-wavelength output laser light. A mobile system, such as a satellite, can also have the photonic, integrated circuit chip as a component thereof.
