Abstract
We propose and demonstrate a magnetless Faraday rotator of a (BiY)3Fe5O12 waveguide with stripe magnetic domains. It has a potential application to compact optical isolators. The specific Faraday rotation angle of −150 deg/cm and the extinction ratio of 13 dB are obtained without a magnet.Keywords
