Dynamic PhotoDiode: the unique light-sensing technology with tunable sensitivity – ActLight Webcast

Traditionally, photodiodes operate at static voltage and obtain incident light intensity from a relatively weak photocurrent. ActLight has introduced a new concept of photodiode operation. The photodiode is used in a dynamic regime where pulsed voltage is applied to it. Light intensity is defined not by magnitude of the measured photocurrent, but by the delay time of appearance of the strong output current with amplitude independent of the light intensity. This brand new and innovative mode of photodiode operation provides a great improvement of device performance that brings light sensing to the next level. This technology is called Dynamic PhotoDiode (DPD).

Thanks to its unique operating principle and its device structure, the DPD is capable of single photon sensitivity with low operation voltage at 1V, which facilitates effective pixel scaling. ActLight’s DPD single photon sensitivity device is a good candidate for Single Photon Avalanche Diode (SPAD) replacement. Recent developments show that the sensitivity of the DPD can be tuned to optimal level taking into account ambient light. 

In this webcast, Yole Développement and ActLight join forces to provide you with their expertise. Yole will introduce the 3D sensing market, an existing market that is bound to grow substantially over the next few years thanks to a wide range of applications.

Meanwhile, ActLight will provide you with an exhaustive explanation of the DPD operating principle and a virtual demo of its unique tunable sensitivity feature.
