Abstract:

Silicon photonics is playing an increasingly important role in the implementation of photonic circuits for the generation and processing of optical and microwave signals. In this talk, techniques to generate and process optical and microwave signals using silicon photonic circuits will be discussed. Specifically,the use of a silicon-based on-chip optical spectral shaper to generate a largely chirped microwave waveform will be discussed. The use of an integrated sidewall phase-shifted Bragg grating to perform all-optical differentiation of an optical pulse, and the use of a silicon-photonic symmetric Mach–Zehnder interferometer incorporating cascaded microring resonators to achieve independently tunable multichannel fractional-order temporal differentiator will also be discussed.
