title: Temperature dependent nonlinearity effects of a QED-200 detector in the visible.
abstract: The spectral response of the United Detector Technologies model QED-200 quantum efficiency detector, along with that of other photodiodes, has been measured for two different wavelengths in the visible. The QED shows a strong temperature dependent response at certain power levels. It is shown that the effect comes from an increase in internal quantum efficiency due to a supralinearity effect at power levels of ~1 mW.
