摘要： A distributed driver for an optic signal generator has a first amplifier cell with one or more amplifiers configured to receive and amplify an input signal to create a first amplified signal. A second amplifier cell has one or more amplifiers configured to receive and amplify the input signal to create a second amplified signal. A first conductive path and second conductive path connects to the first amplifier cell and the second amplifier cell such that the inductance associated with the first and second conductive path counteracts a capacitance associated with the first amplifier cell and the second amplifier cell. A variable capacitor may be part of the first amplifier cell and/or the second amplifier cell to selectively tune the capacitance of the distributed driver. A distributed bias circuit may be part of the first amplifier cell and/or the second amplifier cell to bias an optic signal transmitter.

摘要： A receiving device includes a light source, a wave multiplexer, a converter, a demodulator and a processor. The light source outputs local light. The wave multiplexer causes the local light to interfere with a received signal to acquire an optical signal. The converter converts the optical signal into an electrical signal. The demodulator demodulates the electrical signal to acquire a demodulated signal. The processor is configured to correct an error of the demodulated signal. The processor is configured to acquire a signal correction amount and/or an error rate. The processor is configured to control the light source in order to adjust an output intensity of the local light based on the signal correction amount and/or the error rate.

摘要： A mobile system includes a self-supporting platform, a tunable anti-reflective (AR) skin or film disposed on and secured to the mobile platform, one or more actuators and a controller. The tunable AR skin or film includes one or more layers that are at least partially transmitting to optical energy at one or more optical wavelengths. The skin or film is substantially flexible and/or stretchable and has an optical AR to incident electromagnetic radiation of a given wavelength which is selectively variable when flexed and/or stretched. The actuators are able to flex and/or stretch the skin or film in response to receipt of a control signal. The controller generates the control signal based on a measured value of the electromagnetic radiation transmitted through the tunable AR skin or film.

摘要： Systems and methods for optical narrowcasting are provided for transmitting various types of content. Optical narrowcasting content indicative of the presence of additional information along with identifying information may be transmitted. The additional information (which may include meaningful amounts of advertising information, media, or any other content) may also be transmitted as optical narrowcasting content. Elements of an optical narrowcasting system may include optical transmitters and optical receivers which can be configured to be operative at distances ranging from, e.g., 400 meters to 1200 meters. Moreover, the elements can be implemented on a miniaturized scale in conjunction with small, user devices such as smartphones, thereby also realizing optical ad-hoc networking, as well as interoperability with other types of data networks. Optically narrowcast content can be used to augment a real-world experience, enhance and/or spawn new forms of social-media and media content.
