Abstract:
A semiconductor laser comprising:a waveguide including, a light-emitting quantum well and at least two layers of an optically non-linear material, said non-linear material converting light emitted from said light-emitting quantum well in the waveguide into parametric conversion waves for emission from said waveguide, and said quantum well located within one of the layers of the optically non-linear material and on a mode of the waveguide higher than a fundamental mode of the waveguide, and configured to emit a pump wave as a light for parametric conversion, wherein thickness and optical indices of the at least two layers are such that the wave guide has a modal phase matching condition for parametrical fluorescence between the pump wave emitted by the quantum well and said parametrical conversion waves in the waveguide.
