THE MICROSTRIP LASER

We present a novel semiconductor laser structure, the microstrip laser , where the epitaxial laser layers sit directly above a thick gold lay er, instead of on a conventional semiconductor substrate, This design provides advantages for both high frequency and high-power performance compared to conventional ridge waveguide structures. Results indicati ve of an improved structure are presented, including a factor of 3 red uction in the thermal resistance of the microstrip laser compared to a conventional laser.
