研究了高、低、高折射率（RIs）三层涂层微球中的窃窃廊模式。以内外高ri层为中心的沿海模态和内陆模态以不同的径向模态存在。在合适的RI值和三层厚度下，一个内陆模式和一个海岸模式耦合，产生类似成键和反键轨道的光子场径向分布。耦合发生在比光的波长厚得多的中间低ri层上。在双阱势的一维粒子的量子力学模拟中分析了这种耦合。(c) 2007年美国光学学会。
Whispering gallery modes in a microsphere coated with three layers of high, low, and high refractive indices (RIs) are considered. Coastal modes and inland modes, centered on the outer and inner high-RI layers, exist as different radial modes. At right values of RI and thickness of the three layers, an inland mode and a coastal mode couple to produce a radial distribution of the photonic field that resembles bonding and antibonding orbitals. The coupling occurs across a layer of the middle low-RI layer, much thicker than the wavelength of light. The coupling is analyzed in a quantum-mechanical analog of a one-dimensional particle in a double-well potential. (c) 2007 Optical Society of America.
