Triangular- and square-lattice photonic crystal (PhC) micro-cavities with high quality factor and ultra-small effective modal volume have been widely researched [1, 2]. In this article, we originally proposed a fivefold PhC micro-cavity structure and presented a brief description of its photonic band gap, the characteristics of its defect modes and the(More)
A flexible photonic crystal cavity, consisting of a III-V active layer embedded in a flexible medium, with a line-defect by removing three air holes for nanoscale structural deformation detection is proposed and optimized. The cavity can hold the photonic band-gap modes with the fundamental mode located at approximately 686 nm, overlapping with the(More)
We present studies of two kinds of hybrid plasmonic annular resonators with different cross-sectional shapes of circle and square. Their performance as defined by the Q/V ratio is enhanced considerably with a reduction in their physical dimensions. There exists critical annular radii below which “circle ring” outperforms “square(More)
Photonic crystal (PhC) lasers feature compact mode volume with high quality factor and they are promising candidates for ultra-fast and ultimate thresholdless lasing operation [1]. Until now, most photonic crystal lasers fabricated on silicon [2], III-V [3] and organic hybrid platforms [4] are limited by their natural rigidities. Here we report on a hybrid(More)
