Claims Summary
1. An imaging device comprising:
a plurality of pixel elements, each pixel element including complementary first-type and second-type modulation doped quantum well interfaces that are formed in a resonant cavity on a substrate and that are spaced apart from one another, wherein electromagnetic radiation within a predetermined wavelength range is received at said pixel element and injected into said resonant cavity thereby generating charge that is accumulated in said second-type modulation doped quantum well interface for said pixel element.
