摘要：

An In0.22Ga0.78As/GaAs single quantum-well laser (SQW) integrated monolithically with a surface-emitting harmonic generation (SEHG) segment was fabricated and tested. By coupling an 1.06-mu-m Nd:YAG laser output into the active device, the green surface-emitting light at 0.51-mu-m was observed as the result of nonlinear interactions within the SEHG segment. The nonlinear interaction cross section A(nl) of the device was found to be 2.3 X 10(-7) W-1 which agrees well with theory. The application of the active device as a dense-wavelength-division-multiplexing (DWDM) demultiplexer was demonstrated with a tunable Ti:sapphire laser to simulate the multiwavelength signal source and a CCD detector array to record the spatially separated signals of different wavelength. System resolution better than 2 nm was obtained for the device, which was limited by the short length of the SEHG segment. Potential for a DWDM channel spacing of 10 GHz is discussed.
