Where to Buy Faraday Isolators
Faraday isolators are essentially optical one-way devices, largely blocking radiation only in one direction. They can be used, for example, for protecting lasers and laser amplifiers against optical feedback. There are bulk devices as well as fiber-coupled isolators. Some are polarization-sensitive.
