摘要: Lasing actions are obtained from well-fabricated octagonal quasi-periodic photonic crystal (OQPC) microcavities. The defect modes in OQPC microcavities are investigated and compared with the calculation results obtained using the finite-difference time-domain (FDTD) method. A large single-mode lasing wavelength range over 200 nm without mode hopping and a high side-mode suppression ratio (SMSR) of over 30dB are observed, which result from the mode dependence suppression mechanism on the cavity geometry.
