Paper Abstract

Single-mode InGaAsP QW lasers with wavelengths of 700 to 730 nm are demonstrated. These lasers are attractive as light sources for medical and biological applications because biological tissues are relatively transparent in the near-infrared range. The laser has a 2-micrometer-wide ridge-waveguide structure and achieves single-mode 100-mW CW operation at 80°C with an extremely low operating current of 130 mA and a high characteristic temperature of 182 K. These InGaAsP lasers enable innovative solutions in demanding applications by means of a light source with a compact size and low cost.
