Abstract

Distributed feedback (DFB) lasers currently offer steady single mode emission for a wide wavelength range of applications. 980 nm was used as pump source into a commercially available distributed feedback DFB operating in the 1550 nm wavelength range. The device were characterized experimentally through light output-current-voltage I-V-L measurements and emission spectra at fixed and at various threshold currents and temperatures. In addition, amplification of the device was detected using pump laser at threshold current of Ith=22 mA and room temperature of T=25 oC..
