Abstract

We have fabricated a TE mode InGaAsP active waveguide optical isolator based on the nonreciprocal loss shift in an optical fiber telecommunication wavelength of 1550nm. We demonstrated a TE mode nonreciprocal loss shift of 9.3dB/mm under a magnetic field of +/-1kG in the facricated InGaAsP active waveguide with Fe on an InP substrate at a wavelength of 1560nm. This result opens a way to the monolithic integration of semiconductor-waveguide-type optical isolators with edge emitting semiconductor lasers.
