Fig. 3From: All-Si Photodetectors with a Resonant Cavity for Near-Infrared Polarimetric DetectionThe theoretical results for the polarization properties of the photodetector with the surface plasmonic resonator. a The polarization dependence of optical absorption spectra at different polarization angle. The 0°of polarization angle was defined along the direction of the Au grating. b Polarization-dependent absorption intensity with incident wavelengths of 860 nmBack to article page
