  • Optical detection device for detecting an intensity of a light beam and for detecting data transmitted by the light beam
    Patent number: 7009165
    Abstract: An optical detection device for detecting an intensity of a light beam in a detection window and for detecting data transmitted by the light beam includes a first detection diode and an array of at least two second detection diodes in a detection window. In addition, provision is made for a first readout circuit connectable to the first detection diode, for reading out the first detection diode at a first readout speed to detect the data, and for a second readout circuit connectable to the second detection diodes, for reading out the second detection diodes at a second readout speed smaller than the first readout speed, so as to detect the intensity of the light beam.

  • Photodiode
    Publication number: 20050156182
    Abstract: Apart from a semiconductor substrate and a photosensitive region in the semiconductor substrate, which comprises a space charge zone region for generating a diffusion current portion and a diffusion region for generating a diffusion current portion, a photodiode includes an insulation means in the semiconductor substrate for at least partially confining the diffusion region against an adjacent surrounding region of the semiconductor substrate.
