An anomalous performance has been found in studying the optical response of a QED-100 device against the reverse bias voltage applied to the device. After reaching a saturation value, the optical response suddenly decreases at a given voltage. Further increasing of the reverse bias raises the optical response again, but it never reaches the previous saturation value within the voltage interval studied in this work. The response drop disappeared after eliminating the electrical protection diode of the device, but the optical response still decreases for bias voltages larger than that needed to saturate the response. The decrease depends on wavelength and optical power.
