Mode converting waveguide for heat assisted magnetic recording

Light is excited by a light source in a first waveguide mode. The light is converted to a second waveguide mode via a channel waveguide having a cross-sectional geometry normal to a direction of propagation of the light that rotates a polarity of the first waveguide mode to a second waveguide mode....

Zusammenfassung:	Light is excited by a light source in a first waveguide mode. The light is converted to a second waveguide mode via a channel waveguide having a cross-sectional geometry normal to a direction of propagation of the light that rotates a polarity of the first waveguide mode to a second waveguide mode. The light in the second waveguide mode is delivered to a near-field transducer that provides electromagnetic heating for a heat assisted magnetic recording write head.
