    摘要： A flexible waveguide with an adjustable index of refraction. The core layer and/or the cladding layer of a flexible waveguide may include a plurality of nanoparticles having a different index of refraction than the core layer and/or cladding layer. The plurality of nanoparticles may have an index of refraction that is greater than or less than an index of refraction of either the core layer or the cladding layer in order that the overall effective index of refraction of either the core layer or the cladding layer can be adjusted.

    摘要： A data writing system includes an array of cells for storing data and a write transducer that moves over a selected cell in the array of cells. The write transducer includes a writer producing a write magnetic field that intersects the selected cell. The write transducer also includes a plasmon resonator that is adjacent the writer. The plasmon resonator is shaped to receive lower power density radiation and to provide plasmon radiation at a higher power density to an optical spot intersecting with the selected cell. The plasmon radiation heats the selected cell above a write temperature.
