![]() Insertion Loss and Degree of Isolationįor many applications, a low insertion loss, i.e., a low loss for forward-propagation light, is essential. That phase change depends on temperature and wavelength. Note that a polarization-insensitive isolator will in general not preserve the polarization state (or simply rotate it), since there is an arbitrary relative phase change between the two polarization components. There are also Faraday mirrors in similar housings, having only one fiber port and exhibiting a 90° polarization rotation for reflected light. The photograph was kindly provided by Microwave Photonic Systems, Inc. ![]() Figure 4:Ī fiber-coupled Faraday isolator. Such devices can be fitted into rather compact packages, as shown in Figure 4. ![]() of rutile (TiO 2).īackward-propagating light of any polarization direction can be transmitted, but will appear with an offset beam position (Figure 3, bottom), and will thus not be launched back into the input fiber. Here, the polarizers are birefringent wedges, made e.g. (The beam angles are exaggerated for better clarity.) In a fiber-coupled device, there is an additional lens on each side for collimating and re- focusing the beam.Ī type of device as frequently used in fiber optics is shown in Figure 3. Setup of a polarization-insensitive Faraday isolator, with high transmittance in forward direction (top) and a spatial offset for backward propagation (bottom). The basic principle of a polarization-insensitive isolator is to first spatially separate the orthogonal polarization components of the input beam with some kind of polarizer, then send both through a Faraday rotator, and combine them again in the second polarizer. In particular, optical fiber communication systems are usually operated with undefined polarization state, and Faraday isolators as well as other components are then required to work with arbitrary polarization states. Such devices are often required in the context of fiber optics, because many fibers are not polarization-maintaining. Polarization-insensitive Faraday IsolatorsĪ polarization-insensitive Faraday isolator is a device which works for arbitrary polarization of the input beam. It may be better to optimize that polarizer's orientation for maximum isolation, while accepting a somewhat higher insertion loss in forward direction. If the rotation angle of the Faraday rotator somewhat deviates from 45° (either due to fabrication errors or due to operation away from the design wavelength), the orientation of the output polarizer may still be adjusted for maximum transmission, but in that case the degree of isolation is reduced. Note that the output polarizer (pol 2) is important if light may be reflected back with a modified polarization state. Then, however, its polarization direction is rotated by another 45° in the Faraday rotator, so that this light will be blocked at the input polarizer, or can be sent to the separate output port. When light is reflected back to the output port of the isolator with an unchanged polarization state, it can fully transmit the output polarizer (pol 2).

The double arrows indicate the polarization directions of a forward and backward-propagating beam.Ī selection of Faraday isolators for different power levels. Setup of a polarization-sensitive Faraday isolator, containing a Faraday rotator between two polarizers. Here, a properly polarized and collimated input beam passes a first polarizer (pol 1 in Figure 1) with minimum loss, then a 45° Faraday rotator, and finally another polarizer (pol 2) with its transmitting axis being rotated by 45°, such that the transmission losses are small. The simplest type of Faraday isolator is polarization-sensitive in the sense that it works only when the input beam has a prescribed direction of linear polarization. Light injected into port 1 will exit at port 2, while input at port 2 will be sent to port 3, and input at port 3 to port 1.
