摘要： An efficient multiple-wavelength light emitting device is provided. This multiple-wavelength light emitting device comprises a light emitting layer (4) for emitting light containing wavelength components to be output, a negative electrode (5) that is positioned at the back surface of the light emitting layer and that transmits at least a portion of the light, reflecting layers (7R, 7G, and 7B), positioned at the back surface of the negative electrode, for reflecting, of the light emitted through the negative electrode to the back surface, light having specific wavelengths, which reflecting layers are stacked up in order perpendicularly to the light axis, in correspondence with the wavelengths of the light to be reflected, thus configuring a reflecting layer group (7). In the direction perpendicular to the light axis, divisions are made in any of at least two or more light emission regions which reflect light of different wavelengths. In each light emission region, the distance between the reflecting surface of the reflecting layer (7) on the semi-transparent side and the reflecting surface in the semi-reflecting layer (2) is adjusted in this configuration so that it becomes a resonating optical path length for the light that is emitted in the light emission region.

摘要： An edge-emitting type light-emitting device (11000, 14000) comprises an organic light-emitting layer (40), a pair of electrode layers (30) and (50) for applying an electric field to the organic light-emitting layer (40), and an optical waveguide which transmits light emitted from the organic light-emitting layer (40) to the edge. The optical waveguide comprises a core layer (20) mainly transmitting light, and cladding layers (10) and (60) having a refractive index lower than that of the core layer (20). The core layer (20) may be a layer different from the organic light-emitting layer (40) or may comprise the organic light-emitting layer. A grating (12) is formed in the core layer (20) or in the boundary area between the core layer (20) and the cladding layer (10). A light-emitting device (31000) may comprise an optical fibre section (200). Another embodiment (43000) may comprise a defect and a grating having a one-dimensional periodic refractive index distribution and constituting a photonic band gap.

摘要： A multiple wavelength light emitting device is provided wherewith the resonance strength and directivity between colors can be easily adjusted for balance. This light emitting device comprises a light emission means 4 for emitting light containing wavelength components to be output, and a semi-reflecting layer group 2 wherein semi-reflecting layers 2R, 2G, and 2B that transmit some light having specific wavelengths emitted from the light emission means and reflect the remainder are stacked up in order in the direction of light advance in association with wavelengths of light to be output. Light emission regions A R , A G , and A B are determined in association with the wavelengths of light to be output. The configuration is such that, in the light emission regions, the distances L R , L G , and L B between a reflecting surface for light from the light emission means side of the semi-reflecting layers 2R, 2G, and 2B that reflect light output from those light emission regions and a point existing in an interval from the end of the light emitting layer on the semi-reflecting layer group side to the reflecting layer are adjusted so as to have an optical path length at which that light resonates.

摘要： A light-emitting device (1000) has a light-emitting device section (100) and a waveguide section (200) for transmitting light emitted from the light-emitting device section, which are integrally formed on a substrate (10). The light-emitting device section (100) has a transparent anode (200) which is formed on the substrate (10) and forms a light-transmitting section, a grating which is formed in part of the anode (20), an insulation layer (16) having an opening (16a) facing the grating (12), a light-emitting layer (14) at least part of which is formed in the opening (16a) of the insulation layer (16), and a cathode (22). A waveguide section (200) has a core layer (30) which is formed on the substrate (10) and is integrally formed with the anode (20), and a cladding layer (32) which covers an exposed area of the core layer (30) and is integrally formed with the insulation layer (16). The light-emitting layer can emit light excelling in wavelength selectivity and having directivity, and can be applied to not only displays but also optical communications and the like.
