Abstract

Embodiments of the disclosure provide an optical sensing device for a receiver in an optical sensing system. The optical sensing device includes a light concentrator configured to collect a light beam. The light concentrator includes an input aperture configured to collect the light beam, an output aperture configured to output the light beam, and a side surface in contact with the input aperture and the output aperture. The side surface is configured to reflect the collected light beam towards the output aperture. The optical sensing device also includes a photodetector placed behind the light concentrator. The photodetector is configured to receive the light beam collected through the output aperture and convert the light beam to an electrical current.
