Abstract

This paper presents a novel optical circulator configuration which only employs Faraday rotators to complete light polarization plane’s rotation. By using Jones matrices, the insertion loss and isolation are evaluated. The results show that the isolation is obviously increasing with an increase of the rotation errors of the rotators. A 3-port circulator has been fabricated and achieved an insertion loss lower than 0.8dB and an isolation over 45dB.
