N2 - We demonstrate the 10-Gbit/s direct modulation of optically pumped photonic-crystal (PhC) nanocavity lasers at up to 100°C by using an InGaAlAs multiple-quantum-well (MQW) structure as an active region. The device exhibits an output power exceeding 20 μW and a maximum 3-dB bandwidth of 8.3 GHz at an operating temperature of 100°C. In addition, when the laser is modulated at 10 Gbit/s, low energy costs of 7.2 fJ/bit at 25°C and 23.4 fJ/bit at 100°C are successfully achieved. Thus an InGaAlAs MQW PhC nanocavity laser is a promising candidate for the light source of a photonic network on a CMOS chip.
