LIGHT-EMITTING DEVICE |
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. |
