Abstract
We report on lasing at room temperature and at telecommunications wavelength from photonic crystal nanocavities based on quantum dots. Such laser cavities with a small modal volume and high quality factor display a high spontaneous emission coupling factor . Lasing is confirmed by measuring the second-order autocorrelation function. A smooth transition from chaotic to coherent emission is observed, and coherent emission is obtained at eight times the threshold power.
