Abstract
A signal generator includes a photonic circuit configured to output a sequence of solitons at a known rate. The solitons illuminate a high-speed photodiode that, in response, generates an electrical signal, such as a sinusoidal signal, which can be provided as input to a direct digital synthesizer configured to output successive phases of a selected waveform in response to electrical stimulus.
