Paper Abstract

We have demonstrated distributed-feedback, 1.39 micrometer wavelength InGaAsP/InP, multiple-quantum-well, folded-cavity surface-emitting, laser diodes with a low threshold current of 25 mA. These devices have greater than 45 dB side-mode suppression. Their wavelength tunes continuously with current over an interval of 1.5 angstrom at a rate of 0.11 angstrom/mA (-1.7 GHz/mA). These devices are useful for two-dimensional spectroscopic gas-sensing applications. Employing these compact lasers, we have detected atmospheric water-vapor at 1.3925 micrometer.
