Abstract :
We have measured emission decays from 2D GaAs/AlGaAs multi-layered post/hole array structures using a decay measurement system by femtosecond-laser excitation. We have observed the fast emission decays of the 2D structures in the diagonal and lateral direction. Spectra observed in the lateral direction are shown to be stimulated emission based on the 2D photonic band gap structure
