A novel tunable infrared detector based on a quantum ballistic channel
We consider the possibility of infrared signal detection using photon-induced intersubband scattering in a quantum ballistic channel (QBC). Our calculations show that light absorption in a QBC with a non-uniform narrowed end can lead to a photovoltaic effect. Using mode matching techniques, the photocurrent is obtained. Evaluations of the responsivity, detectivity and bandwidth of the proposed photovoltaic detector are favorable for practical applications.
