Basic Principles of Digital Photodiode

 
 

Digital photodiodes are photoelectrical elements, meaning they convert light to electricity. They can also be driven with a voltage to produce a small amount of current in the absence of a light source. Once light hits the digital photodiode, the current increases significantly, similar to a solar cell. If you look at the current-voltage curve for a digital photodiode, it has the same shape as the current-voltage curve for a solar cell. A digital photodiode acts like a simple light sensor, where the sensitivity can be controlled with an applied voltage.

 
 

When a digital photodiode is driven with some voltage in the absence of illumination, it will behave like a typical rectifying diode. At low applied bias, there is a small amount of saturation current (called the dark current) that will flow through the device. Just like a typical diode, a digital photodiode has some breakdown voltage in reverse bias.

 
 

Once a digital photodiode is illuminated, the behavior of the device depends on whether there is a bias applied to the digital photodiode, as well as the polarity. The IV curve for the device will scale with the applied voltage. A digital photodiode has two modes of operation: photovoltaic mode (when run in forward bias) and digital photodiode mode (when run in reverse bias).
