摘要

A novel room temperature terahertz photodetector based on EIT is proposed. The main idea for operation in room temperature and THz ranges is related to convert the incoming long-wavelength IR signal to short-wavelength field through EIT phenomena. For realization of the idea we use 4-level quantum well structure. In the proposed structure the electromagnetic field of terahertz-infrared radiation interfere with the electromagnetic field of short-wavelength probe field and this effect modifies the absorption characteristic of probe field. This means that the terahertz detection is translated to short-wavelength detection which has small dark current. So, the proposed idea is appropriate for terahertz and high temperature applications.
