摘要： A time division multiplexing (TDM) facility is presented for time division multiplexing at least two inter-system channel (ISC) data streams to create a TDM multiplexed data stream. The TDM multiplexed data stream can be forwarded across the network over a single wavelength of a wavelength division multiplexing (WDM) network. The TDM multiplex data stream may be wavelength division multiplexed with one or more other TDM multiplexed data stream. Different protocols are presented for maintaining disparity balance within the ISC data streams depending upon whether a given sequence in one of the data streams is an idle sequence, frame sequence or continuous sequence.

摘要： A method and system for dispersion control of electromagnetic signals in communication networks by narrowing the widths of electromagnetic pulses such as modulated laser signals. Generally, in the preferred embodiment, the present invention utilizes a feedback loop based on dither frequency modulation which dynamically adjusts the alignment of the laser center frequency with the filter passband. In this way, there is an acceptable tradeoff between optical power and pulse width, so a higher power laser can be used to generate a narrower optical pulse. The narrower pulses then travel farther in the fiber link before reaching their dispersion limit. It is believed that, by using this invention, existing link distance could be doubled, while re-using existing installed singlemode fiber. The systems employing the feedback loop may be information carrying or control systems.

摘要： A silicon oxynitride (SiON)/silicon dioxide (SiO2) optical waveguide switch with a wavelength locked feedback control loop which monitors the wavelength of UV radiation produced by a UV tunable laser diffraction grating write source which has passed through a UV bandpass filter and is then used to selectively write a diffraction grating in the optical waveguide switch. The diffraction grating structure can be switched on or off at will, resulting in an optical switch element for IR radiation traveling through the optical waveguide. This optical switch element is a basic building block which can be used for many other systems, such as optical logic gates or all-optical cross connect switches for wide area networks. Further, it may be used to selectively tap off a portion of the optical signal, for example to read header information in a data stream (or packets) which indicates the destination switch port of the optical data, without disrupting the remaining optical data.
