Abstract
An optical scanning system comprises an optical scanning device and a photoreceiver device. The optical scanning device includes a first waveguide array including a plurality of first waveguides through which light beams propagate and from which the light beams are emitted as emission light in an emission direction crossing a propagation direction of the light beams. The photoreceiver device includes a second waveguide array including a plurality of second waveguides disposed in areas on which, when the emission light from the plurality of first waveguides is reflected as reflected light from a target object, the reflected light is incident, the plurality of second waveguides configured to receive the reflected light to propagate the received reflected light as propagating light beams. An array pitch of the plurality of first waveguides in the optical scanning device differs from an array pitch of the plurality of second waveguides in the photoreceiver device.
