Faraday Rotator
Kohoku Kogyo manufactures Faraday rotators by using the liquid phase epitaxial (LPE) method with lead free flux. Faraday rotator is used to non-reciprocal devices such as optical isolator and optical circulator in optical communication system. They can also be applied to optical sensors in non-optical communication fields.
Features
- Lead-free
- High extinction ratio
- Low loss
