摘要	A laser structure may be used to fabricate a plastic laser and achieve electrically-driven lasing action. The structure comprises an LED, a waveguide laser, and a substrate disposed between them. The substrate has a first and a second side. Light emitted from the LED is received by the substrate at the first side and concentrated as it is guided with the body of the substrate to the second side, where it is received by the laser. Concentration of the light across the substrate improves the efficiency of the device and leads to lower threshold powers.
其他摘要	激光器结构可用于制造塑料激光器并实现电驱动激光作用。该结构包括LED，波导激光器和设置在它们之间的基板。基板具有第一和第二侧。从LED发射的光在第一侧被基板接收，并且在其被基板的主体引导到第二侧时被集中，在那里它被激光器接收。衬底上的光的集中提高了器件的效率并导致较低的阈值功率。
主权项	An article comprising a laser structure for providing a source of electromagnetic radiation, the laser structure comprising: a light-emitting device comprising a plurality of layers including two spaced-apart conductive layers and a light emissive layer therebetween such that incoherent radiation of a first wavelength is emitted from the light emissive device, a substrate disposed adjacent the light-emitting device and having a first and a second side, the substrate being so oriented relative to the light-emitting device that incoherent electromagnetic radiation of the first wavelength emitted from the light-emitting device is received by the substrate at the first side and guided within the body of the substrate to the second side, wherein the substrate is configured such that the radiation is concentrated as it is guided within the body of the substrate from the first side to the second side, and a laser comprising a first and a second cladding region with a core region therebetween, the laser disposed such that the radiation guided to the second side of the substrate is received by the laser, the core region comprising a layer of material selected to absorb the incoherent radiation of the first wavelength and to emit coherent electromagnetic radiation of second wavelength, longer than the first wavelength, in response to the absorbed incoherent electromagnetic radiation; the substrate configured to concentrate the radiation by the substrate comprising at least a first and a second region with a reflective interface proximal the junction of the first and second regions for internally reflecting light within the first region, the substrate being so oriented relative to the light-emitting device that a substantial amount of the incoherent electromagnetic radiation of the first wavelength emitted from the light-emitting device is received by the first region at the first side of the substrate, wherein the radiation is internally reflected at the interface to be substantially confined within the first region and is guided within the first region to the second side of the substrate.
