Abstract
The behavior of an optical isolator based on the Faraday effect of an absorbing magneto-optical material is analyzed, taking into account th e effect of magnetic circular dichroism (MCD). MCD is indissolubly con nected with Faraday rotation and limits the maximum obtainable isolati on ratio through elliptization of the polarization of the incident bea m. A formula is derived to calculate this effect and applied to a prac tical example.
