Abstract

A compact Faraday effect optical isolator was constructed for visible wavelengths and tested at 5145 A. The nonreciprocal element of the isolator was polycrystalline zinc selenide placed in the magnetic field of a permanent magnet. For 5145 A the isolator had a 2.06-dB insertion loss and a 25.5-dB isolation. Indices of refraction and Verdet constants were measured for zinc selenide in the wavelengthregion from 4700 to 6300 A.

摘要

构建了一种用于可见光波长的紧凑型法拉第效应光隔离器，并在5145埃波长下进行了测试。该隔离器的非互易元件是置于永久磁铁磁场中的多晶硒化锌。对于5145埃波长，该隔离器的插入损耗为2.06分贝，隔离度为25.5分贝。测量了硒化锌在4700至6300埃波长范围内的折射率和费尔德常数。
