Abstract
We report on the demonstration of optically pumped photonic crystal lasers with InAs quantum dot active regions operating at room temperature near 1310 nm. Absorbed threshold pump powers as low as 25 μW are observed. We also extract a characteristic temperature of 17 K, which is attributed to limitations caused by surface recombination.
