Abstract

The effect of non-reciprocal loss/gain in semiconductor-ferromagnetic-metal hybrid was studied. It is shown that the optical loss/gain of this semiconductor-ferromagnetic-metal hybrid differs for the forward and backward propagation when the magnetization is perpendicular to the light propagation and lies in the film plane. Using this effect a new design of optical isolator is proposed, which is beneficial for monolithic integration of optical isolator with laser diode. The non-reciprocal loss was experimentally observed in Ga1-xAlxAs waveguide covered by Co for the first time.
