The influence of magnetooptical crystal linear birefringence on the parameters of an optical isolator

摘要

Theoretical considerations have been realised by using a matrix method and by investigating a magnetooptical crystal under simultaneous influence of two magnetic fields: the first one, parallel to the direction of the light propagation (Faraday configuration) and the second one orthogonal (Cotton-Mouton configuration). An experiment confirms theoretical expectations, namely the possibility of extending the isolation magnitude by parallel arrangement of transmission axis of the input polarizer to the birefringence axis.
