(a) Typical photocurrent spectra for TM (red) and TE (blue) light, together with that of 45 degree edge facet device (green). (b) Experimental (upper, blue) and simulated (lower, red) cavity mode dependence on wavelength for TM light. The experimental curve is the photo-responsivity spectrum divided by the quantum well absorption curve (). (c) Similar curves as (b) for TE light. The error bars show the large noise at wavelength larger than 15 μm in experiment. (d) Calculated intensity distribution of the square of electric field component in z direction of LSP cavity mode for TM light, |E_z,TM|², within the cavity. (e) Similar distribution as (d) for SPP cavity mode.
