Three-section distributed Bragg reflector (DBR) lasers emitting in the 1.5-?m wavelength region are characterized for use as a light source in a spectrometer for gas analysis. The three-section DBR lasers facilitate a wide, continuous tuning range while preserving the output power at a constant level. Typical characteristics for three-section DBR lasers and potentials and limitations of these lasers in gas-monitoring applications are discussed. A fiber optic system for high-sensitivity gas detection using wavelength-tunable DBR lasers is also presented.
