Reduced divergence angle of photonic crystal vertical-cavity surface-emitting laser

, 2009
The reduced divergence angle of the photonic crystal vertical-cavity surface-emitting laser (PC-VCSEL) was investigated in both theory and experiment. The photonic crystal waveguide possessed the weakly guiding waveguide characteristic, which accounted ...

Time-resolved spectra of a self-pulsing quantum dot laser

, 2010
Self-sustained pulsations in the output of an InAs quantum dot laser diode in the MHz range are reported for the first time. The characteristics (shape, range and frequency) are presented for the free running laser and when optical feedback in the ...
