Abstract
A magneto-optic modulator modulates signals from a superconducting circuit such as a single-flux-quantum (SFQ) logic system onto a carrier wave light beam. The modulator is formed by depositing a magneto-optic material such as EuSe onto a superconducting ground plane such as that of the circuit. A microwave microstrip line is formed on the magneto-optic material and carries a signal from the circuit. The signal induces an H field in the magneto-optic material which causes the magneto-optic material to modulate the light.
