Title: Optical isolator
Inventor: KUME HIROSHI
IPC: G02B27/28
Filed: 1990-06-07
Abstract: PURPOSE:To attain free control over a maximum isolation temperature position by obtaining maximum isolation by using specific wavelength for actual in-use wavelength. CONSTITUTION:Variation in angle of Faraday rotation due to fine temperature variation DELTAT becomes equivalent to wavelength variation shown by DELTAlambda-(KT/Klambda)DELTAT when compensated by variation due to wavelength variation DELTAlambda, where KT is the temperature coefficient of the angle of Faraday rotation and Klambda is a wavelength coefficient. The optical isolator which is so assembled as to have the maximum isolation with lambda+ or -DELTAlambda wavelength at room temperature TR has the maximum isolation at temperature TR+ or -DELTAT when operating with practical wavelength lambda. Consequently, the maximum isolation temperature can be controlled and high isolation is obtained within the practical temperature range.
