Elimination of depolarization in a Faraday isolator based on a rotator with natural optical activity
Abstract:
It is proposed to use a magnetoactive medium with natural optical activity in a Faraday isolator. Such a device will enable polarization optical isolation which, in the first approximation, will be insensitive to the small perturbations of permittivity, leading to linear birefringence in the magneto-optical element. This approach is promising for isolators for short-wave radiation, powerful radiation, large-aperture isolators, as well as for isolators with high requirements for the isolation ratio. Media on the basis of which such isolators can be implemented in various wavelength ranges are discussed. The experimental verification demonstrates the operability of the proposed idea.
