Abstract: In one embodiment, an apparatus includes a wavelength-shifting element configured to receive an input-light signal. The wavelength-shifting element includes a wavelength-shifting material configured to absorb at least a portion of the received input-light signal and produce an emitted-light signal from the absorbed portion of the received input-light signal. The apparatus also includes an optical-concentrating element configured to receive at least a portion of the emitted-light signal and concentrate the received portion of the emitted-light signal onto a photodetector. The apparatus further includes the photodetector configured to receive the concentrated portion of the emitted-light signal and produce an electrical current corresponding to the concentrated portion of the emitted-light signal.

Abstract: Various of the disclosed embodiments incorporate wavelength-shifting (WLS) materials to facilitate high data rate communication. Some embodiments employ a waveguide incorporating such WLS materials to receive a wireless signal from a source. The signal may be, e.g., in the optical or ultraviolet ranges, facilitating a ˜10 Gbps data rate. Because the WLS material is sensitive in all directions, the source may be isotropic or wide-angled. The WLS material may be shaped into one or more “bands” that may cover an object, e.g., a head-mounted display. A detector may be coupled with the bands to receive the wavelength-shifted signal and to recover the original signal from the source. The WLS material may be modified to improve the waveguide retention, e.g., by incorporating layers of material having a different reflection coefficient or a Bragg reflector.
Abstract translation: 各种所公开的实施例结合了波长移位（WLS）材料以便于高数据速率通信。 一些实施例采用包含这样的WLS材料的波导从源接收无线信号。 信号可以是例如在光学或紫外范围内，有助于10Gbps的数据速率。 因为WLS材料在所有方向都是敏感的，所以源可以是各向同性的或广角的。 WLS材料可以被成形为可以覆盖物体的一个或多个“带”，例如头戴式显示器。 检测器可以与频带耦合以接收波长移位信号并从源恢复原始信号。 可以修改WLS材料以改善波导保持，例如通过引入具有不同反射系数的材料层或布拉格反射器。

Abstract: Systems and methods for optical communication through air or space are disclosed. A method includes encoding one or more data frames with a data-link layer forward error correction (FEC) code to produce a plurality of encoded data frames and transmitting the plurality of encoded data frames from a transmitter (TX) to a receiver (RX) at least partially through air or space using a plurality of optical beams. The RX identifies a corrupted encoded data frame and reconstructs the corrupted encoded data frame using a data-link layer FEC decoder operating over a plurality of non-corrupted encoded data frames.

The apparatus also includes a focusing element configured to receive at least a portion of the emitted-light data signal, concentrate the received portion of the emitted-light data signal, and produce a concentrated-light data signal. The apparatus further includes a photodetector configured to receive the concentrated-light data signal, and produce an electrical current corresponding to the concentrated-light data signal.
