Abstract
The continuous-wave (cw) operation of GaInNAsSb lasers at 1560 nm is reported. Light-current measurements were made before and after a 100 h cw burn in at 20°C, during which a 3 x 890 _m2 device with 72 mA initial threshold current and 14 mW maximum output power experienced a 15% drop in peak output power. These preliminary lifetime results provide insight into the reliability of GaInNAsSb active regions and reinforce the promise of this material for C-band devices. High-resolution modal gain spectra were extracted from the amplified spontaneous emission spectra acquired after the burn in, providing reliable values for the internal loss, transparency current, and differential gain.
