摘要： An optical access network comprises an optical network unit having a first port for connecting to a first optical link, a second port for connecting to a second optical link and an optical source. The optical source is arranged to generate a first optical signal, to transmit the first optical signal via the first port, to receive an optical seed signal via the first port and to amplify the optical seed signal. The optical seed signal has a narrower bandwidth compared to the first optical signal. A modulator is arranged to modulate the amplified optical seed signal with upstream data to form an upstream optical signal and to transmit the upstream optical signal via the second port. A polarisation modifier can modify polarisation of the first optical signal.

摘要： Systems and methods for optical communication using single source optical transmission are disclosed. A representative method includes receiving optical signals at a first frequency by a receiver (RX) from an optical fiber. The received optical signals are routed to a modulator that modulates the optical signals at a second frequency. The optical signals are emitted by a transmitter (TX) back to the optical fiber at the second frequency.

摘要： The invention relates to electronic data carriers having non-volatile memory, and to a method for short-range optical communication. The aim consists in creating a simple, compact, jam-resistant data carrier and a data read/write device. A primary source of radiation is placed in a first device, and a second optoelectronic device is used in a passive mode, in which it receives power as a result of photovoltaically converting the energy of an absorbed portion of the radiation from the first device and responds to a query from the first device by means of modulating a reflected portion of the radiation. The devices are brought into contact in such a way that a light guide is formed between an active structure of the first device, i.e. an optical transceiver, and an active structure of the second device, i.e. a target, said light guide concentrating radiation in a communication channel between the devices.

摘要： A laser array mux assembly generally includes an array of laser emitters coupled to an optical multiplexer, such as an arrayed waveguide grating (AWG), with an external partial reflector after the multiplexer. Each of the laser emitters may include a gain region that emits light across a range of wavelengths including, for example, channel wavelengths in an optical communication system. The AWG filters the emitted light from each of the laser emitters at different channel wavelengths associated with each of the laser emitters. The reflector reflects at least a portion of the filtered light such that lasing occurs at the channel wavelengths of the reflected light. The laser array mux assembly may be used to generate an optical signal at a selected channel wavelength or to generate and combine optical signals at multiple channel wavelengths.
