Abstract (en)
An edge emitter (110) with a cap (112) on top of a (transparent electrode-insulating film-active film-insulating film-reflective electrode) stack (114-122) has a refractive index substantially matched to that of the active film (118). The cap (112) is thicker than the active film (118) and is made of a material with an attenuation lower than that of the active film (118) material. An emitting side surface (132) of the cap (112) is more transmissive than its other side surfaces (134-138) and its top surface (130). A significant portion of the electroluminescent radiation from the active film (118) entering the cap (112) is re-directed towards the emitting side surface (132) and thereby radiated from the edge emitter (110). <IMAGE>
