ABSTRACT:
There is provided a light-emitting module which suppresses wavelength drift. A light-emitting module according to the invention includes a stem and a cap fixed to the upper surface of the stem. A thermo-electric cooler is mounted on the stem and a base is mounted on the thermo-electric cooler. A laser diode is mounted on one side of the base. A thermistor that measures the temperature of the laser diode is mounted on another side. The other side includes an overhung portion that blocks radiant heat transmitting from the cap toward the thermistor.
