碩士 === 中華大學 === 電機工程學系(所) === 97 === Recent advances in nanotechnology-based manufacturing have made it possible to manufacture optical resonators having physical dimensions of the order of the optical wavelength. Accurate numerical simulations can provide a detailed understanding of the characters of optical microcavities and allow for design optimization before devices are fabricated. This purpose is to develop time-domain numerical algorithms for modeling electromagnetic wave interactions with linear and nonlinear optical gain media, as well as dispersions. FDTD techniques is used to study these phenomena and simulate the numerical modeling of microcavity lasers directly from the time-dependent Maxwell's equations. Simulations obtained the gain spectrum, Q-factor and finesse of microcavity resonator. The computational method will be served as a tool to develop useful components in future high-intensity photonic integrated circuits applied in optical communications.
