ABSTRACT
We observe the effect of localized field reduction (LFR) in visible light photon counters (VLPCs) by measuring the bias current of the device after a light pulse, and find it consistent with being produced by avalanches that have an average transverse dimension of ≈12 μm2. The characteristic recovery time for the device after an avalanche is measured to be ≈3.5 ms, and is a function of bias voltage and temperature. A simple model is presented to describe the performance drop of the VLPCs with rate as a consequence of LFR.
