Description:
The SMPMOD.LDM DFB laser module is packaged in an
industry-standard 14-pin butterfly package. The integrated thermoelectric cooler and thermistor are used to temperature stabilize and tune the laser to the desired wavelength.

Reference Cell:
Gas-filled photodiode reference cell acts as a back-facet monitor and can be used by control circuitry to wavelength lock and power monitor the laser diode.

Temperature Control:
Integrated TEC provides heating and cooling of the laser chip from +10° to +70°C. An NTC thermistor is mounted close to the laser chip to accurately monitor laser temperature.
