High quality factor microcavity lasers realized by circular photonic crystal with isotropic photonic band gap effect

The photonic band gap PBG effect and its isotropy of sunflower-type circular photonic crystal CPC are obtained and investigated from the transmission spectra performed by finite-difference time-domain FDTD method. The PBG directional width variation is found to be only 6.7%. A well-confined whispering gallery mode WGM with azimuthal number of 6 is obtained by FDTD simulation from the CPC microc...

Photonic crystal heteroslab-edge microcavity with high quality factor surface mode for index sensing

In this report, we propose a photonic crystal heteroslab-edge microcavity design for optical index sensing, where the high quality Q surface mode is confined by mode-gap effect. By optimizing the barrier region of the microcavity, high Q factor of 6.6 105 is obtained in simulations. Lasing actions with high Q factor and low threshold of 6400 and 0.55 mW are obtained from the real devices. High ...
