摘要： An optical multiplexer (10) that multiplexes a plurality of light beams having different wavelengths includes a first waveguide (101) that receives first-wavelength light, a second waveguide (102) that receives second-wavelength light having a shorter wavelength than the first-wavelength light, a third waveguide (103) that receives third-wavelength light having a shorter wavelength than the second-wavelength light, a first multiplexer (110) in which the light propagates between the first waveguide (101) and the second waveguide (102), and a second multiplexer (120) in which the light propagates between the first waveguide (101) and the third waveguide (103). The second-wavelength light is propagated to the first waveguide (101) at the first multiplexer (110). The third-wavelength light is propagated to the first waveguide (101) at the second multiplexer (120).

摘要： A light-emitting structure includes a substrate, a sub-pixel stack, a cover layer over the sub-pixel stack, and at least one interface between the substrate and the cover layer. The at least one interface has an interface roughness. The sub-pixel stack includes an emissive layer between a first transport layer and a second transport layer, a first electrode layer coupled to the first transport layer, and a second electrode layer coupled to the second transport layer. The sub-pixel stack is over the substrate and configured to emit light including a scattering component caused by the interface roughness and a cavity component separate from the scattering component. A ratio of a luminance of the scattering component to a luminance of the cavity component increases with a viewing angle relative to a display normal. An optical power of the scattering component is a fraction of an optical power of the cavity component.

摘要： To provide (i) a two-lens optical system, (ii) a beam combining module, (iii) a projector, and (iv) a method for assembling a two-lens optical system each of which allows for an improved lens positioning sensitivity [Means to Attain the Object] A two-lens optical system (100) includes a first lens (1) for use in collimation adjustment, the first lens being configured to move along only an optical axis of light emitted from a light source; and a second lens (2) for use in beam steering, the second lens being configured to move along only two axes perpendicular to the optical axis.

摘要： A light-emitting structure includes a substrate, a sub-pixel stack over a surface of the substrate, and a bank including a first bank portion and a second bank portion. The sub-pixel stack has an emissive stack including an emissive layer between a first transport layer and a second transport layer, a first electrode layer coupled to the first transport layer, and a second electrode layer coupled to the second transport layer. The second bank portion is between the first bank portion and the sub-pixel stack, and the bank surrounding at least the emissive stack and the first electrode layer forms an interior space above the sub-pixel stack.

摘要： An image display device includes a drive circuit substrate, micro LED elements, and a wavelength conversion layer that converts excitation light emitted from the micro LED elements and that emits converted long-wavelength light to a side opposite to the drive circuit substrate, the micro LED elements and the wavelength conversion layer being sequentially stacked on the drive circuit substrate. The micro LED elements include a first multilayer film that reflects the long-wavelength light converted by the wavelength conversion layer.
