Title:
OPTICAL SCAN DEVICE, OPTICAL RECEPTION DEVICE, AND WAVEGUIDE ARRAY
Document Type and Number:
WIPO Patent Application WO/2018/061231
Kind Code:
A1
Abstract:
A waveguide array is provided with a plurality of first waveguides arranged in a first direction. Each of the plurality of first waveguides is provided with an optical waveguide layer through which light propagates in a second direction crossing the first direction or a direction opposite to the second direction, a first mirror which has a first reflection surface crossing a third direction, and extends in the second direction, and a second mirror which has a second reflection surface facing the first reflection surface of the first mirror, and extends in the second direction. The third direction crosses a virtual plane parallel to the first and second directions. The optical waveguide layer is located between the first mirror and the second mirror. The refractive index and/or thickness of the optical waveguide layer changes. The first mirror has a higher optical transmittance than the second mirror, transmits part of the light propagating through the optical waveguide layer and emits the transmitted light in the third direction from the opposite side to the first reflection surface.
