我们通过数值模拟证明,利用时域有限差分(FDTD)方法分析了具有高、低、高三层折射率(RI)的微球谐振器中的回音壁模式(WGMs)。为了使光耦合进入以及……
We numerically demonstrate that whispering-gallery modes (WGMs) in a microsphere resonator with three layers of high, low and high refractive index (RI) are analyzed by using the finite difference time domain (FDTD) method. To make the light couple in and out of the microsphere, a phase matched waveguide is used to overlap the WGMs evanescent radiation field. By changing the gap between the microsphere and waveguide, the WGMs of two high-RI layers are efficiently excited. The stored energy and the mode volume are optimized for sensing applications. The coupling structure reveals a good sensitivity of 38.29 nm/RIU (RI unit).
