Abstract :
We present the design, fabrication, and characterization of quantum dots-in-a-well infrared detectors integrated with a planar metamaterial layer. The resonantly excited metamaterial layer provides strongly enhanced optical fields and the increased photocurrent is obtained at the metamaterial resonant frequency.
