Description
Magneto fiber optic switch has been widely researched due to its capabilities handling large beam cross sections, operating at low voltages, featured as low insertion loss and intrinsic non-reciprocity.
A magneto optic switch, comprising: a plurality of optical components positioned in order along a light path comprising: a single fiber optical collimator, a first birefringent optic crystal, a first half wave plate assembly, a polarization rotation assembly, a second half wave plate assembly, a second birefringent optic crystal, and a dual fiber optic collimator.
