We report new results on the design, fabrication and characterization of a novel midinfrared sensor called quantum dot avalanche photodiode (QDAP). The QDAP consists of a quantum dots-in-a-well (DWELL) detector coupled with an avalanche photodiode (A

There are many applications where the ability to detect optical signals in the 1.65 - 3 μm wavelength range would be of considerable interest. In this paper we discuss two technologies that offer considerable promise for high speed, high sensitivity
