Photoluminescence modification by high-order photonic band with abnormal dispersion in ZnO inverse opal
Heeso Noh, Michael Scharrer, Mark A. Anderson +2
We measured the angle- and polarization-resolved reflection and photoluminescence spectra of ZnO inverse opals. Significant enhancement of spontaneous emission is observed. The enh…
Wave interference effect on polymer microstadium laser
W. Fang, H. Cao
We investigate the lasing modes in fully chaotic polymer microstadiums under optical pumping. The lasing modes are regularly spaced in frequency, and their amplitudes oscillate wit…
Tuning the shape of semiconductor microstadium laser
W. Fang, G. S. Solomon, H. Cao
We presented a detailed experimental study on lasing in GaAs microstadium with various shapes. Unlike most deformed microcavities, the lasing threshold varies non-monotonically wit…
Statistics of random lasing modes and amplified spontaneous emission spikes in weakly scattering systems
X. Wu, H. Cao
We have measured the spectral correlations and intensity statistics of random lasing modes in weakly scattering systems, and compared them to those of the amplified spontaneous emi…
Effect of local pumping on random laser modes
X. Wu, J. Andreasen, H. Cao +1
We have developed a numerical method based on the transfer matrix to calculate the quasimodes and lasing modes in one-dimensional random systems. Depending on the relative magnitud…
