Abstract: A visible light communication system includes a light transmitter including a group III nitride semiconductor laser element and a wavelength converter provided to face a light exit surface of the nitride semiconductor laser element and containing a fluorescent material. The visible light communication system further includes a wavelength filter configured to remove light emitted from the fluorescent material and a light receiving element configured to receive light emitted from the group III nitride semiconductor laser element via the wavelength filter.
