摘要 | A light-emitting device (1000) includes a light-emitting device section (100) and a waveguide section (200) which transmits light from the light-emitting device section, and the light-emitting device section and the waveguide section are integrally formed on a substrate (10). The light-emitting device section (100) has a transparent anode (20) which form up a light-propagation section and an optical section (12) formed in part of the anode (20) which are formed on the substrate (10), a first dielectric multilayer film (11a), an insulation layer (16) having an opening (16a) facing the optical section (12), a light-emitting layer (14), at least part of which is formed in the opening (16a) of the insulation layer (16), a cathode (22), and a second dielectric multilayer film (11b). The optical section (12) forms a one-dimensional photonic band gap and has a defect section which is set so that the energy level caused by defects is within a specific emission spectrum. The light-emitting device can emit light excelling in wavelength selectivity and having directivity, and can be applied not only to displays but also to optical communications and the like. |
其他摘要 | 发光装置(1000)包括发光装置部分(100)和透射来自发光装置部分的光的波导部分(200),并且发光装置部分和波导部分一体形成在基板(10)上。发光装置部分(100)具有形成光传播部分的透明阳极(20)和形成在基板(10)上形成的阳极(20)的一部分中的光学部分(12),第一电介质多层膜(11a),具有面向光学部分(12)的开口(16a)的绝缘层(16),发光层(14),其至少一部分形成在开口(16a)中)绝缘层(16),阴极(22)和第二电介质多层膜(11b)。光学部分(12)形成一维光子带隙并具有缺陷部分,该缺陷部分被设定为使得由缺陷引起的能级在特定发射光谱内。发光装置可以发出波长选择性优异且具有方向性的光,并且不仅可以应用于显示器,还可以应用于光通信等。 |
