Chinese Abstract

本研究提出一可應用於積體光路之新型二維光子晶體多模干涉功率分光器。藉由調整結構中輸出波導區第一根中間介質柱之位置,而達到提高元件工作帶寬之目的。經有限差分時域法分析,結果顯示相較傳統多模干涉功率分光器,本研究分光器之傳輸波譜於長波長波段處之半傳輸截止波長有大幅提升之優點,而可將元件工作帶寬有效提升達28%。

English Abstract

We propose a novel multimode interference-based two-dimensional photonic crystal power splitter that can be applied to photonic integrated circuits. Through fine tuning the position of the leading central dielectric column between the two output waveguides, we substantially increase the bandwidth of the power splitter. Based on the simulations with the finite different time domain method, we find that the transmission spectra of the proposed splitter have a much higher upper 3db cut-off wavelength than the conventional multimode interference-based photonic crystal power splitter has, and the bandwidth of the proposed splitter is effectively increased up to 28%.
