光スキャンデバイス、光受信デバイス、および光検出システム
Document Type and Number:
Japanese Patent JP7108933
Kind Code:
B2
Abstract:
An optical scanning device includes a waveguide array including a plurality of waveguide elements arranged in a first direction. Each of the plurality of waveguide elements includes: an optical waveguide layer that propagates light supplied to the waveguide, in a second direction intersecting the first direction; a first mirror extending in the second direction and having a first reflecting surface that intersects a third direction, and a second mirror extending in the second direction and having a second reflecting surface that faces the first reflecting surface of the first mirror. The optical waveguide layer is located between the first mirror and the second mirror and has a variable thickness and/or a variable refractive index for the light. The width of the first mirror in the first direction and/or the width of the second mirror in the first direction is larger than the width of the optical waveguide layer in the first direction. The first mirror has a higher light transmittance than the second mirror and allows part of the light propagating through the optical waveguide layer to be emitted in the third direction.
