| Abstract: | This paper demonstrates a monolithic 1.3-μm/1.5-μm wavelength demultiplexing photodetector fabricated using Ar ion laser-assisted metal organic molecular beam epitaxy (MOMBE) growth. Reduction of crosstalk to -24 dB is accomplished in both 1.3-μm and 1.5-μm wavelength regions. The dependence of the crosstalk on the coupling efficiency between the fiber and device and the polarization dependence of the responsivity is also discussed |
