Title: Temperature-stable Faraday rotator material and its use in high-performance optical isolators
Abstract: The temperature characteristics of Faraday rotator material Y3xGd3(1−x)Fe5O12 are discussed. The material with YIG molar fraction x between 0.57 and 0.7 has a small temperature coefficient of the Faraday rotation and is suitable for isolators with temperature-stable isolation. The extinction ratio of the Faraday rotator can be minimized by selecting an appropriate polarization direction of light incident on it. This polarization direction should also be selected by taking the temperature dependence into account. Isolators using the material as a rotator hold isolation to >40 dB throughout the temperature range from 0 to 50°C.
