Reconfigurable Low-Phase Noise Frequency Generation up to 92.5 GHz in a Monolithically Integrated Silicon Photonics Circuit

Abstract

A silicon photonics chip is successfully employed for frequency multiplication of an 18.5-GHz clock up to 92.5GHz (×5) with low additional phase noise. The chip includes a 20-GHz phase modulator for comb generation and a thermally tunable distributed feedback resonator for reconfigurable spectral mode selection.
