Optical signal distribution in waveguide-coupled metal-smiconductor-metal detector arrays
Abstract
We report the use of waveguide-coupled GaAs metal-semiconductor-metal (MSM) photodetectors for signal distribution in an optoelectronic matrix switch. The power delivered to multiple detectors that are plated in-line on a single AlGaAs waveguide can be balanced by varying the detector lengths along the propagation direction and by controlling the degree of coupling between the waveguiding and absorbing layers. The dependence of the coupling …
