Abstract

We have proposed a new dual band quantum cascade photodetector with ability of detecting UV and IR through two independent paths. Because of large band gap of GaN and AlGaN, we have used Al_xGa_1-xN/AlN quantum wells. For detecting of IR and UV intersubband and interband transitions have been used respectively. For IR and UV path we have achieved peak of Responsivity about 60 mA/W at 2.7 um and 25 mA/W at 245 nm at 300K respectively.
