The experimental demonstration of a novel integrated optical isolator concept is presented. By using a transversely magnetized ferromagnetic metal as the electric contact of an active waveguide structure, the transverse magneto-optic Kerr effect induces non-reciprocal loss of the TM guided mode. Based on this principle we designed, fabricated and characterized the first version of an optical isolator easily integrable with standard InP-based active devices. Experimental results on these first demonstrators show an isolation ratio of 2.0 dB/mm.
