Abstract: An optical scanning device includes: a first mirror; a second mirror opposed to the first mirror; two non-waveguide regions sandwiched between the first mirror and the second mirror; an optical waveguide region disposed between the two non-waveguide regions; and two intermediate regions. The average refractive index of the optical waveguide region is higher than the average refractive index of each intermediate region. The average refractive index of each intermediate region is higher than the average refractive index of each non-waveguide region. The first mirror allows part of light propagating through the optical waveguide region to be emitted as emission light in a third direction. By changing the refractive index and/or thickness of the optical waveguide region, the third direction, which is the emission direction of the emission light, is changed.

Abstract: An optical scanning device comprises a waveguide array, a first adjusting element, a plurality of phase shifters, a second adjusting element, and a control circuit. When light emitted from the waveguide array forms a light spot on a virtual plane that is spaced apart from the waveguide array, the control circuit causes the light spot to move in first and second directions such that the distance of movement of the light spot from start to finish of scanning of a target region is greater in first one of the first and second directions than in second one of the first and second directions.

Abstract: A light-emitting device comprises a layered structure between a first layer and a second layer. The first first layer has a refractive index n1 for first light having a wavelength λa in air. The second layer has a refractive index n2 for the first light. The layered structure comprises: a photoluminescent layer having a first surface facing the first layer and a second surface facing the second layer; and a surface structure disposed on at least one selected from the group consisting of the first surface and the second surface of the photoluminescent layer. The refractive index n1 and the refractive index n2 are lower than a refractive index nwav-a of the photoluminescent layer for the first light. The layered structure has an effective thickness to more strongly emit TE polarized light than TM polarized light.
