Excitation of a near-field transducer using combined transverse electric and transverse magnetic modes

摘要

A method involves receiving light from a light source at a fundamental transverse electric (TE₀₀) mode or a fundamental transverse magnetic (TM₀₀) mode. A waveguide polarization multiplexes the light to a combined mode that includes the TM₀₀ mode and a first higher-order transverse electric (TE₁₀) mode. A near-field transducer is excited via the light at the combined mode.
