The response of current-voltage characteristics of the photo memory cell with quantum dot and quantum well are presented. It has good low-light-level sensitivity and very small dark current at low temperature. In order to explore its high sensitive application because of high internal photoconductor gain, the CMOS readout circuits and correlated double sample structure are integrated to acquire small...
The authors report on a new method using a delayed self-homodyne set-up to determine the frequency response of a photoreceiver. The laser diode used here must not be calibrated. This method turns out to be very exact and easy to realise. It uses the frequency modulation of the laser diode with low modulation frequencies and large frequency deviations to produce a well-defined (nearly white) optical...
