Conference paper


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.
