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