Abstract
An opto-sensitive device, a pixel configured for use in an opto-sensitive device, and a method of operating an opto-sensitive device are disclosed. The opto-sensitive device illustratively includes a capacitor stacked on top of a photodetector, thereby improving the fill factor of the opto-sensitive device. Transparent properties of the capacitor for a wavelength of interest ensure that the incident light is completely or mostly absorbed only within the photodetector and not within the capacitor.
