Pixelated Photon Detector

PD07

One of the most promising recent developments in the field is that of devices consisting of large arrays (O(103 )) of tiny APD’s packed over a small area (O(1 mm2 )) and operated in a limited Geiger mode [16]. Among different names used for this class of photodetectors, “PPD” (for “Pixelized Photon Detector”) is most widely accepted (formerly “SiPM”). (PDG Review section )

Beyond silicon

Device Structure

• The key to characterize the sensor.• Not many discussion on it comparing with the

evaluations…– QE vs wave length, higher geometrical factor..– Lower cross talk– Timing property– Vbreak– Gain, capacitance.

• Next time at least one session should be devoted to this issue.
