Fig. 2: Photon detection performance of the sensor.

From: Photon-efficient camera with in-sensor computing

Fig. 2

Photon count rate and dark count rate of 25 pixels of the sensor, the positive and negative bias currents correspond to the same count, a 405 nm b 1550 nm. c The sensor generates positive and negative pulses respectively under positive and negative bias currents, and the pulse width and pulse amplitude increase as the bias current increases. d With the increase of incident light intensity, the photon count of each pixel increases linearly. The photon counts of all pixels are displayed stacked.
