Abstract
Several applications such as free space communication, laser radar, and night vision require a single mode, single-frequency laser with an optical power of ~1 W and a wavelength of 1.55µm Recently, high power InGaAsP/InP tapered lasers [1][2] were obtained at this wavelength with a single lateral mode, but still with numerous longitudinal modes. Here, we report on a high-power tapered AlGaInAs/InP distributed Bragg reflector (DBR) tapered single frequency laser.
