Abstract

A novel photodiode for application in a standing- wave interferometer was developed. The operation principle is based on the optical standing wave whose stationary intensity profile can be detected by a photosensor which - for this purpose - has to be transparent and thinner than the optical wavelength. The working principle and basic design requirements of the developed sensor are described, and the results of measurements inside and outside the standing wave are discussed.
