摘要： Disclosed are systems and methods for improving wavelength control in tunable laser sources. Embodiments of the systems and methods include delivering a fraction of the light output from the laser to an optical filter subsystem. The optical filter subsystem is capable of outputting at least one filter response signal, and comprises 2 complementary optical etalon filters with nominally identical free spectral ranges but offset by nominally one third of the free spectral range. The filter response signal is processed in a control unit which executes a control algorithm to generate a tuning signal that is used to control the wavelength of the laser.

摘要： Optical networks interconnect a plurality of optical network units (ONUs) to an optical line terminal (OLT). The OLT comprises a plurality of optical transceivers that are wavelength division multiplexed and connected to a WDM metro network. The metro network is configured to facilitate communication of a plurality of wavelengths between the OLT and local nodes, the local nodes including a wavelength sharing network configured to connect at least one of the wavelengths communicated with the OLT to a plurality of feeder fibers. The feeder fibers connect the wavelength sharing network to remote nodes that comprise WDM devices that have pluralities of output ports. An optical combiner allows the first and second ONUs to share the same transceiver in the OLT.

摘要： A novel overlay networking method designed specifically to handle the large file transfers that constitute a large and growing portion of media-rich Internet traffic is disclosed. The proposed system and method uses large (e.g., 10 MB) packets or Media Frames (MF) and orderly concatenations of these frames into chains (MC) to achieve a considerable reduction in power consumption relative to current IP Internet routers. Transmission of each MC is scheduled, while individual MFs are routed directly in interstices within MCs.

摘要： The present invention relates to an optical upconverting or downconverting gain or loss modulating mixer and a receiver for subcarrier optical communication systems using this mixer. The optical mixer can be formed, for example, from an optical amplifier including a semiconductor laser chip comprising a p-n junction with an active region channel formed along the junction. An optical signal received from the communication system is directed into one end of the channel, and a combination of a D-C bias signal and a local oscillator signal is concurrently impressed on the chip to gain-modulate the received optical signal and produce an upconverted or downconverted output signal. In the receiver, the upconverted or downconverted output signal from the gain-modulated optical amplifier is detected by a photodetector, amplified if necessary, filtered and then demodulated before transmission to the output utilization device. A loss modulator provides similar optical mixing but does not provide a gain to the output signal.

摘要： A passive optical network is provided that spectrally slices optical signals transmitted in both upstream and downstream directions utilizing wavelength division multiplexing routing. The passive optical network preferably includes an incoherent signal source at both ends to provide signals that are spectrally sliced according to optical frequency. The downstream information may be transmitted in a conventional data format. The upstream transmissions may be segregated by subcarrier multiplexing, time scheduling or wavelength division multiplexing.

摘要： A passive optical network architecture is disclosed for application in a local loop telephone environment. A local digital switch transmits an optical signal bearing information downstream over an optical fiber to the terminal equipment of a group of subscribers. This transmitted optical signal comprises light at a number of different wavelengths, i.e., it is a wavelength-division multiplexed signal, where each subscriber is associated with a particular wavelength of light. Each subscriber's terminal equipment detects that portion of the transmitted optical signal that exists at its assigned wavelength and thereby recovers the information sent by the local digital switch for that subscriber. However, a fraction of this detected optical signal is then remodulated by the subscriber's equipment with the subscriber's upstream information and returned to the local digital switch. As a result, no optical sources exist in the subscriber equipment in this optical network architecture.
