Abstract :
A heterogeneous photonic crystal cavity structure based on the band edge mode is reviewed. The outer photonic bandgap region is introduced to contain the central band edge mode in order to minimize in-plane losses. Lasing modes are identified from the spectral position and polarization characteristics, and compared with theoretical calculations based on the three-dimensional finite-difference time-domain method.
