Figure 3

(a) Experimental resonance wavelength dependence on the metal patch. Also shown is the simulated map of in the QW layer as a function of the metal patch length L and wavelength. (b) Experimental responsivity enhancement factor (blue dots) of the cavity LSP mode (taken from the responsivity peaks of the PMC-QWIP devices with different metal patches) and the simulated of the LSP mode in the QW layer (black square) as a function of the resonance wavelength. The line is to guide the eye. (c) Photocurrent spectra under different incident angles. (d) Photocurrent spectra with different incident polarizations. Curves are vertically shifted for clarity.
