Novel Single-Sideband Modulator in Silicon on Insulator Technology with Widely Tunable Carrier-to-Sideband Ratio for Broadband RF Signals

Abstract

A compact silicon photonics single-sideband modulator with continuously tunable carrier-to-sideband ratio and large spurious sideband rejection of 40 dB is demonstrated using a single phase modulator, sideband selection through photonic integrated filter, and carrier re-insertion. Operation with a 5 Gbps ASK-modulated 16.5 GHz carrier is reported.
