    摘要: A light-emitting device that includes an LED and a light extraction layer and the method for making the same are disclosed. The LED includes a substrate on which an active layer is sandwiched between a p-type layer and an n-type layer, the active layer generating light in a band of wavelengths about a central wavelength when holes and electrons recombine therein. The n-type layer, active layer, and p-type layer are formed on the substrate. First and second electrodes for providing a potential difference between the p-type layer and the n-type layer are included in the LED. The light extraction layer includes a clear layer of material having a first surface in contact with a surface of the LED and a second surface having light scattering features with dimensions greater than 0.5 times the central wavelength. The material of the clear layer can be polycrystalline or amorphous.

    摘要: A method for high-volume production of light emitting diodes with attached lenses involves providing pre-fabricated lenses, wherein the pre-fabricated lenses are held by a common transfer structure, simultaneously attaching the pre-fabricated lenses to respective ones of light emitting diodes, and releasing the pre-fabricated lenses from the common transfer structure. In an embodiment, the light emitting diodes are distributed in a pattern on a common substrate and the common transfer structure is configured to hold the pre-fabricated lenses in a pattern that corresponds to the pattern of the light emitting diodes on the common substrate. Further, to attach the pre-fabricated lenses to the light emitting diodes, the common transfer structure is positioned relative to the common substrate such that the pre-fabricated lenses are aligned with the light emitting diodes.

    摘要: A light emitting device and photodetector combination having a structure in which the layer of the photodetector that contacts the light emitting device is separated from the light emitting device by a native semiconductor oxide layer that is both insulating and has a refractive index lower than that of the light emitting device and the photodetector. This configuration results in a light emitting device and photodetector structure that minimizes the capture of the spontaneous emission light output from the light emitting device by the photodetector while electrically isolating the light emitting device from the photodetector. The electrical isolation of the light emitting device from the photodetector results in a four terminal device in which the light emitting device and photodetector may be independently biased, and can therefore be operated at a very low bias voltage.
