  • Abstract
    Ultra-low-threshold semiconductor diode lasers were fabricated by forming buried heterostructures from MBE-grown graded-index waveguide, separate-confinement heterostructure (GRIN-SCH) wafers. CW threshold currents as low as 2.5 mA for 250 ¿m cavity length, output power as high as 20 mW/mirror and external quantum efficiency as high as 80% were obtained.
