Room-temperature photonic crystal laser in H3 cavity on InGaAsP/InP slab
, 2008 We fabricate and investigate two-dimensional photonic crystal H3 microcavities in an InGaAsP slab. The lasing action at room temperature is observed. The lasering threshold is 7mW under the pulsed pump of 0.75% duty cycle.

Simulation study on the coupling behaviors of parallel photonic crystal slab structures
, 2007 過去相關的光子晶體平板結構研究中，研究的內容著重於共平面光子晶體缺陷結構之間的相互作用。在本研究中，我們引進了平行光子晶體平板結構之觀念，來探討在全反射與光子晶體侷限效應共同作用下，共平面光子晶體與平行平板光子晶體結構耦合作用之差異。 我們先利用時域有限差分法來獲得單層平板光子晶體缺陷共振腔與線缺陷波導結構之光子帶隙結構，接著我們模擬得到平行平板光子晶體缺陷共振腔之頻率響應，且觀察電磁場在這種光子晶體垂直耦合中的場型與相位分佈，我們並探討耦合係數對於平板結構之間的距離及厚度的影響。 隨後 ...

A Photonic Crystal Slab Laplace Differentiator
, 2017 We introduce an implementation of a Laplace differentiator based on a photonic crystal slab that operates at transmission mode. We show that the Laplace differentiator can be implemented provided that the guided resonances near the $\Gamma$ point exhibit
