Abstract
In this letter it is pointed out that a substantial improvement in the effective quantum efficiency of ordinary photodetectors can be obtained by simply tilting the detector surface to Brewster´s angle. The technique is best applied to laser heterodyne systems in which the light is linearly polarized, and for which the quantum efficiency directly determines the system sensitivity.
