The Optilab DFB-15XX-PM is coupled with Polarization Maintaining fiber. 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 Mach Zehnder Interferometer (MZI) modulation, DFB-15XX-PM can be used for external modulation application. This MQW DFB laser features Up to 40 mW of output optical power, high Side Mode Suppression Ratio (SMSR). It features in excellent polarization extinction ratio (PER) and a built-in thermoelectric cooler, thermistor, and a rear-facet monitor photodiode for external optical power control. Contact Optilab for more information.
