When linearly polarized light is reflected from the polished surface of a magnetized medium its polarization vector rotates and becomes somewhat elliptical. WebIn an optical system that has time-reversal symmetry, an optical signal can be run backward in time without changing the reality of the physics. This is not possible if the medium involved is nonreciprocal or it has a loss or gain. However, there is a difference between the two possibilities that causes the time-reversal symmetry to break down. can bubble wrap insulate pipes

Electro-Optical Effect - an overview ScienceDirect Topics

WebA considerable advantage afforded the electro-optic effect relative to frequency conversion is the removal of the phase-matching requirement between the fundamental and the generated fields because the frequency of these two optical waves are identical. WebA magneto-optic effect is any one of a number of phenomena in which an electromagnetic wave propagates through a medium that has been altered by the presence of a quasistatic magnetic field.
