Popis:	In this paper, based on effective mass method, we study the absorption characteristics of InAs/GaAs quantum ring photodetector in terahertz range. To enhance the absorption in active region of this photodetector we propose a metallic Fabry-Perot resonant cavity with Au nanoslits as top reflector and Au film as the bottom mirror. It is shown that with this structure at frequency of ~7.1 THz, absorption can be enhanced about 55 times.
