Tunable cross-coupling evanescent mode optical devices and methods of making the same

摘要: Tunable cross-coupling evanescent mode optical devices and methods of making the same are described. In one aspect, a tunable device includes first layer, second metal layer disposed between layers, an electrode. The is supportable electromagnetic field modes over range wavelengths that target wavelength range. electrode has index refraction adjustable values. layers at least corrugated film region with corrugation periodicity enabling equal within localized on opposite sides different respective wavenumbers. have determined in part by substantially unaffected
