 We demonstrate high efficiency and low loss frequency shifters and beam splitters that are controlled using only a single-tone microwave drive, featuring an efficiency of 90%, on-chip insertion loss of 0.45 dB, shift ratio of >99%, and a shift frequency of 30-GHz. Furthermore, we demonstrate cascaded electro-optic frequency shifter, in which light flows through a ladder of energy levels to form a cascaded frequency shift. We shift the light for 120 GHz using only a 30-GHz continous and single-tone microwave.
