摘要
Using laterally patterned metal gratings, single mode operation of 1.3 mum InAs/GalnAs quantum dot lasers has been achieved. At room temperature the lasers exhibit threshold currents as low as 17 mA, output powers of zip to 8 mW (cw) and very stable single mode emission with side mode suppression ratios of well above 40 dB.
