WebIn the consequent analysis of this L3 cavity, it was found that the Qcan be further increased by a slight change of the overall hole radius. This brought the maximum FDTD-computed Qof the design, obtained for R= 0:255ainstead of 0:25a, to 20:9 106 (GME-computed Q: 20:0 106). The resonance frequency of this cavity mode is !=(2ˇ) = 0:254a=c, which, WebThe L3 cavity Q-factor peaks at ˘9x103when n clad= 3:2. These are a remarkable results since these values lie within the highlighted range of n for AlGaAs alloys, opening up the possibility to implement high- Q photonic crystal cavities in standard epitaxial semiconduc- tor heterostructures in GaAs/AlGaAs material systems.
