Abstract
Systems, methods, and apparatus for optical switching. In some implementations, a magneto-optic switch includes multiple optical components positioned in order along a light path including: 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, wherein a first side of the polarization rotation assembly near the first half wave plate assembly includes a first Faraday rotator element, a second side of the polarization rotation assembly near the second half wave plate assembly includes an optic rotation component, the polarization rotation assembly having a magnetic field generating component outside the first Faraday rotator element.
