Abstract: Methods and systems are described for conversion of an optical signal. The device may comprise a conversion layer comprising a nonlinear optical material with a surface structure disposed to receive a pump signal and cause a bound states in the continuum (BIC) optical mode. The conversion layer may be configured to convert, based on nonlinear interaction with the BIC optical mode, an incoming signal incident on the conversion layer from an incoming wavelength to a target wavelength.

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.
