A temperature controlled optoelectronic device includes an optoelectronic transducer having an active area, an electronic cooling device, on which the optoelectronic transducer is mounted, and a temperature sensor installed in the electronic cooling device. The temperature sensor and the electronic cooling device control a temperature of the optoelectronic transducer. A surface of an electronic cooling device directly contacts a base of the optoelectronic transducer for efficient thermal coupling. When the temperature sensor for monitoring the temperature of the optoelectronic transducer is directly attached to a substrate of the electronic cooling device, e.g., to an inside surface of a plate on which the optoelectronic transducer is mounted, the temperature of the optoelectronic transducer can be accurately sensed and adjusted to a precise target temperature.
