Abstract

Middle-wavelength infrared focal plane array (FPA) based on InGaAs/InGaP quantum dot infrared photodetectors (QDIP) was demostrated. It was observed that QDIP showed a high detectivity of 3.62×10 ¹⁰ cmHz ^1/2/W at a temperature of 95 K. It was also observed that QDIP had a low quantum efficiency due to the small fill factor of quantum dots across a single epitaxial layers. The results show that thermal imaging could be achieved at temperatures as high as 120 K.
