The potential use of highly strained GaInAs/GaAs quantum well lasers in high capacity singlemode fibre datalinks is discussed. Heatsink-free CW operation of 1.2 µm GaInAs/GaAs ridge waveguide lasers is demonstrated, with a characteristic temperature T0 of 140 K. The lasing wavelength was > 1.25 µm, which is the longest wavelength reported so far for GaInAs/GaAs systems. A preliminary experiment using 12 µm lasers for singlemode fibre data transmission is also performed.
