In many applications, active temperature control improves the performance of optoelectronic devices. In most solid-state detectors, noise decreases with operating temperature. Responsivity also varies with operating temperature and therefore must be stabilized through active temperature control, if a high degree of radiometric accuracy is required. The operating characteristics of diode lasers also vary considerably with temperature. Emission wavelength, threshold current and operating lifetime all are strong functions of device temperature.
