UT-King’s optical isolator is used in sophisticated lightwave systems where one cannot allow light reflection that might perturb the laser oscillator. Of course, to maintain system performance one wishes to introduce an optical isolator, but the cost sometimes prevents this. The principle of the isolator is illustrated in Fig. 16. The Faraday rotator rotates the polarization of incident light by 45°. Then the reflected light can be cut off by the polarizer at the input end while the transmitted light passes through the analyzer at the exit end. Lead glass is used for the short-wavelength region and YIG (Y2Fe5O12) for the long-wavelength region. A device with 1 dB of insertion loss and 30 dB of isolation is developed for wavelength multiplexing communications.
