Numerical optimization of high-Q-factor photonic crystal microcavities with a graded air lattice

Multi-directional ultra-high sensitive pressure sensor based on the integration of optimized double 60° bend waveguides and modified center-defect photonic crystal microcavity

“…Here PhC microcavity is achieved by adding a nanohole in the center of the H 2 -cavity [31]. Additionally, the three outer holes on the two sides of the defect are modified to improve in-plane confinement of light, while the other holes remain constant.…”

Computing of the quality factor in a two dimensional photonic crystal microcavity

“…Resonance states with high Q factor have been measured at wavelengths near 1.36 µm. In reference [21], we have proposed a filter composed of one microcavity and two waveguides in the PC with a triangular lattice of air holes in silicon. Devices that are structure based on microcavities have been studied using direct input and output coupling through channel waveguides including size-graded holes on both sides of the microcavitiy.…”
