Abstract
- A photodetector pixel using a photonic crystal structure incorporating photoconductive layers has been realized. The fabricated device exploits mode discrimination and resonant cavity enhancement to provide simultaneous multispectral detection capability, high quantum efficiency, and dramatically suppressed shot noise. Detectivities as high as 2.6×1010 and 2.0×1010cmHz1∕2W−1 at the two preselected wavelengths, 632 and 728nm, were achieved, respectively.
