Resonant leaky-mode optical devices and associated methods

摘要: Optical devices with versatile spectral attributes are provided that implemented one or more modulated and homogeneous layers to realize leaky-mode resonance operation corresponding spectral-band design. The first and/or higher multiple evanescent diffraction orders applied excite leaky modes. one- two-dimensional periodic structure, fashioned by proper distribution of materials within each period, can have a resulting symmetric asymmetric profile permit broadened variety resonant be realized. Thus, the optical device permit, among other things, adjacent, distinct frequencies wavelengths produced, convenient shaping reflection transmission spectra for such accomplished, wavelength locations precisely controlled so as affect extent which modes interact other. Further, asymmetry allows precise spacing interactive provide greater flexibility in
