Imbert-Fedorov effect
The Imbert-Fedorov effect (named after Fedor Ivanovič Fedorov and Christian Imbert ) is an optical phenomenon that occurs during the total reflection of circular or elliptically polarized light : the reflected beam experiences a small shift perpendicular to the plane of incidence. The effect occurs together with a shift along the plane of incidence, the Goos-Hänchen effect , which can also be observed with linearly polarized light.
description
If one considers the case of a laterally limited beam which is totally reflected at the interface of two different media, it is noticeable that the total reflection is accompanied by two separate shifts in the longitudinal and transverse directions to the plane of incidence. The existence of a longitudinal shift was already predicted by Isaac Newton and experimentally investigated by Fritz Goos and Hilda Hänchen in the 1940s ; this longitudinal shift is known as the Goos-Hänchen effect. In 1955, FI Fedorov wrote that a transverse displacement of a totally reflected beam should also occur. This lateral shift was calculated in 1972 by C. Imbert with the help of the energy flow argument and was later verified experimentally.
