Abstract

An optical transmitter includes a superconducting driver circuit including at least one Josephson junction, the superconducting driver circuit having a voltage output and having a connection to a circuit ground, a first bias circuit coupled to the voltage output of the superconducting driver circuit, a second bias circuit, wherein the second bias circuit establishes a positive bias voltage relative to the circuit ground, and an electro-optic device having a first end and a second end, wherein the first end of the electro-optic device is coupled to the voltage output of the superconducting driver circuit, and wherein the second end of the electro-optic device is coupled to the second bias circuit.
