Abstract:
Implementations disclosed herein allow a magneto-optical polarization rotator to couple light from a light source of a HAMR recording device to waveguide attached to a slider. According to one implementation, the magneto-optical polarization rotator has a magnetophotonic crystal structure with a number of thin film layers configured to rotate the light by 90 degrees.
