Phase-Controlled Photocurrents in Semiconductors
We show that one can optically control the photoresponse of semiconductor devices by the phase of the EM incident radiation. This can be achieved by interfering two phase-locked quantum pathways, both projecting the same initial bound state to the same energy level in the continuum. An experimental study on quantum well infrared photodectectors is presented.
