ABSTRACT:
One embodiment of the present method and apparatus encompasses an apparatus that may have: a predetermined length, the self-imaging semiconductor waveguide having first and second opposed sides; quantum wells disposed within the self-imaging semiconductor waveguide along the length of the self-imaging semiconductor waveguide, the quantum wells being formed of a quantum well gain material; microchannel cooler that extends substantially the width of the self-imaging semiconductor waveguide, the microchannel cooler located adjacent the first side of the self-imaging semiconductor waveguide; and a plurality of pump arrays arranged along the microchannel cooler opposed from the first side of the self-imaging semiconductor waveguide; wherein the quantum well gain material is photopumped through the microchannel cooler.
