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.
