Monolithically integrated dual wavelength photodetector based on a step shaped F
A novel long wavelength photodetector with dual-wavelength spectral response is designed and fabricated using a step-shaped Fabry-P′erot (F-P) filter structure. The step-shaped GaAs/AlGaAs distributed Bragg reflectors and the InP PIN photodetector are grown on a GaAs substrate using low pressure met
