  • Publication number: 20160258583
    Abstract: This disclosure provides devices, apparatuses and methods of providing an optical filter with quantum dot films for converting a first wavelength of light to a second wavelength of light. The optical filter includes a plurality of high refractive index layers and a plurality of low refractive index layers alternatingly disposed between the high refractive index layers. Quantum dots are dispersed in either the high refractive index layers or the low refractive index layers. In some implementations, the quantum dots are capable of absorbing blue light and emitting green light. Thus, the optical filter can be part of a red-green-blue lighting device that includes a first blue LED optically coupled with the optical filter to produce green light, a red LED and a second blue LED.

  • Publication number: 20070295981
    Abstract: Light-emitting devices (e.g., LEDs) and methods associated with such devices are provided. The devices may include a first pattern and a second pattern which are formed at one or more interfaces of the device (e.g., the emission surface). The patterns may be positioned such that light generated by the device passes through the interfaces of the patterns when being emitted. The patterns can be defined by a series of features (e.g., vias, posts) having certain characteristics (e.g., feature size, depth, periodicity, nearest neighbor distance, etc.) which may be controlled to influence properties of the light emitted from the device, including improving extraction and/or collimation of the emitted light.

  • Publication number: 20030072009
    Abstract: An optical instrument may include a tunable free-space filter as a wavelength selector. That optical instrument may be an optical spectrum analyzer (OSA). Indeed, the OSA may be constructed and arranged as an optical channel monitor for wavelength-division multiplexed optical communication systems. The tunable free-space filter may be a tunable thin film filter (TTFF). The TTFF may be thermo-optically tunable. The tunable filter may be a multi-layer film structure incorporating thin film semiconductor materials. The temperature, and hence the wavelength, of the TTFF may be controlled by various heating and cooling structures. Various TTFF structures are also possible. The TTFF may have a single-cavity Fabry-Perot structure or may have a multi-cavity structure. Packaging variants can also be made. Any one or more of several calibration aids can be included, such as an external source of one or more known wavelength signals, or an internal source of one or more known wavelength signals.
