Abstract :
In this paper, we have developed a new QPM approach for Faraday rotation by utilising an upper-cladding that periodically alternates between MO and non-MO media. Careful selection of materials of similar refractive index ensures that the required waveguiding and phase-matching conditions are achieved and scattering losses are minimised. Moreover, this method requires a mono-directional magnetic field only, eliminating edge effects and simplifying the magnetisation process. We have developed fabrication techniques, now making the integration of a Faraday-rotator optical isolator with a conventional semiconductor laser
