Description
The photon-driven nature of the transport in terahertz quantum cascade laser can be exploited to detect light. Responsivities higher than 16 V/W are demonstrated on a patch-array antenna coupled device. The ~ps lifetimes also allows ultrafast operation. Preliminary studies suggest bandwidth higher than 5 GHz.
