Microwave photonic signal processing using silicon photonic Bragg gratings

Abstract

Waveguide Bragg grating (WBG) devices on silicon constitute a particularly attractive solution for optical and microwave photonics (MWP) signal processing, thanks to their flexibility in producing arbitrarily defined amplitude and phase responses, by directly acting on perturbations of the grating profile, together with their high compactness compared to other integrated photonic filters. This talk will give a brief overview of advances in the field of integrated WBGs applied to microwave photonics and optical signal processing, with emphasis on a number of recent demonstrations. Examples of applications include THz‐bandwidth optical pulse shapers, wideband tunable RF filters, broadband true‐time‐delay lines and phase shifters, and instantaneous frequency measurement systems on‐chip.
