摘要： A fiber optic array is miniaturized in a configuration that includes an input collimator, a first birefringence crystal, a waveplate, a Faraday rotator, a second birefringence crystal and a second collimator. The elements are aligned along a common optical axis. A light beam along the optical axis that is passed through the first collimator emerges off of the optical axis and through the remaining elements. It re-emerges from the fiber optic array on axis. The configuration provides substantial attenuation in a backward direction.

摘要： The present invention relates to the. use of optimized magnet design, magnetic circuit design and wire coil design to improve latching reliability and reduce driving current for the switchable Faraday rotator devices. The geometrical parameters of semi-hard magnet are optimized to produce maximal magnetic field at the location of magneto-optic crystal and hence improve latching reliability and reduce driving current. The wire coil is optimized in coil length, wire gauge, and number of turns to produce most efficient energy transfer and hence reduce driving current and driving voltage. To reduce magnetic energy loss, soft magnetic material is included to form a magnetic conductive close loop and further reduces driving current requirements.
