Abstract:
An optical wireless communication system includes an optical wireless transmitter configured to emit a discrete-time signal of first light, second light, and third light having different wavelength spectra; and a light-receiving sensor including an optical wireless receiver including first, second, and third photoelectric conversion devices configured to convert discrete-time signals of the first, second, and third light beams into first, second, and third photoelectric conversion signals, respectively, wherein the second photoelectric conversion device at least partially overlaps the first photoelectric conversion device, and the third photoelectric conversion device at least partially overlaps at least one photoelectric conversion device of the first photoelectric conversion device or the second photoelectric conversion device, and at least one photoelectric conversion device of the first photoelectric conversion device, the second photoelectric conversion device, or the third photoelectric conversion device includes an organic light absorbing material, a quantum dot, or a combination thereof.
