The Optilab DFB-1531-DM-3 Directly-Modulated (DM) DFB laser is a high-speed 1531 nm wavelength laser source for 3 GHz analog or 4 Gb/s digital transmission optical link. Built with Distributed Feed-Back Grating (DFB) as cavity reflector, it provides pure, single longitudinal mode, hopping free and extremely stable wavelength source. This laser diode is fabricated with Multiple Quantum Well (MQW) for excellent reliability and stability. It can be used for CW operation for fiber sensor or coherence interferometer. Or with direct current modulation DFB-1531-DM-3 can be used for DC to 3 GHz analog or up to 4 Gb/s digital modulation. The wavelength choice is from 1529 to 1561 nm. This MQW DFB laser features Up to 20 mW of output optical power, good Side Mode Suppression Ratio (SMSR) and a builtin thermoelectric cooler, thermistor, and rear-facet monitor photodiode for external optical power control.
