Abstract :
Photonic crystal based nanolasers have sprung a lot of interest in the latest years due to the high optical confinement of the cavity. High quality factor cavities in conjunction with low electromagnetical volumes, allows to implement a significant enhancement of the spontaneous emission dynamics and hence a preferential funnelling of spontaneously emitted photons into the laser mode. Theoretical predictions on such lasers with high spontaneous emission coupling factors beta include a smooth transition from spontaneous to stimulated emission, but also high large signal modulation bandwidth.
