Abstract: An optical filter includes a filter array including filters two-dimensionally arrayed and a band-pass filter. The filters includes first and second filters. A transmission spectrum of each of the first and second filters has local maximum values of transmittance at three or more wavelengths included in a first wavelength region. The band-pass filter passes light in a second wavelength region including two or more wavelengths of the three or more wavelengths and not including one or more wavelengths of the three or more wavelengths. The filter array and the band-pass filter are disposed so that (a) the band-pass filter is located on an optical path of light that passes through the first and second filters or (b) the first and second filters are located on an optical path of light that passes through the band-pass filter.

Abstract: An optical scanning device includes a waveguide array including a plurality of waveguides arranged in a first direction. Each waveguide includes: an optical waveguide layer that propagates light supplied to the waveguide in a second direction intersecting the first direction; a first mirror having a first reflecting surface intersecting a third direction; and a second mirror having a second reflecting surface that faces the first reflecting surface. The optical waveguide layer is located between the first and second mirrors and has a variable thickness and/or a variable refractive index for the light. The width of the first mirror and the width of the second mirror are each larger than the width of the optical waveguide layer. 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.

Abstract: An illuminator includes a light-emitting element and a light extraction sheet which transmits light occurring from the light-emitting element. The light-emitting element includes a first electrode having a light transmitting property, a second electrode, and an emission layer between the first and second electrodes. The light extraction sheet includes a light-transmitting substrate having a first face and a second face, a first light extraction structure on the first face side of the light-transmitting substrate, and a second light extraction structure on the second face side of the light-transmitting substrate. The first light extraction structure includes a low-refractive index layer and a high-refractive index layer having a higher refractive index than the low-refractive index layer. The second light extraction structure is arranged so that light which is transmitted through the light-transmitting substrate and arrives at an incident angle of 60 to 80 degrees has an average transmittance of 20% or more.
