摘要： A system and method for precisely controlling the wavelength selective function provided by fiber Bragg gratings in optical fiber elements. The system and method exploits a wavelength-locked loop servo-control circuit and methodology that enables real time adjustment of the grating pattern being written to said fiber optical link element by a grating writing source to thereby mutually align a center wavelength of the peaked wavelength selective function resulting from the grating pattern with a center wavelength of the optical signal transmitted over a communication channel provided by the fiber. A real-time adaptive dispersion compensation technique for optical fibers is additionally provided that exploits the wavelength-locked loop servo-control circuit. In the adaptive compensation system, a tunable Bragg grating pattern is re-written to the fiber optical link element by a grating writing source under control of the wavelength-locked loop servo-control circuit in order to mutually align a center wavelength of the peaked wavelength selective function resulting from the grating pattern with a center wavelength of an optical signal to be transmitted over the channel.

摘要： A system and method for automatically attenuating optical signals transmitted in optical systems. The system and method exploits a wavelength-locked loop servo-control circuit and methodology that enables real time mutual alignment of the center wavelength of an optical signal having a peaked spectrum function and transmitted through the optical system, and a center wavelength of a wavelength selective device such as an optical filter element implementing a peaked passband function. The wavelength-locked loop servo-control circuit and methodology particularly is capable of real-time aligning the center wavelength of an optical signal in a range between maximum overlap with the center wavelength of the peaked passband function of the optical filter for maximum transfer of output optical signal by the filter element and minimum overlap with the peaked passband function of the optical filter so that output optical signal may be attenuated in the optical system.

摘要： A pluggable connector capable of connecting a large number of electrical transmission lines per connector, and small enough to enable a large number of connectors to be added to a multi-chip module. For example, 5 or 6 of these connectors can add over a hundred coaxial cables to a module. Improved I/O communications is added to a module by such coaxial cables, since they can communicate very high frequency signals in noise prone environments. The pluggable connector is embedded in a multilayer module (e.g. ceramic or glass) for conveying digital information to transmission lines internal or printed on the surface of a module. Each connector contains a receptacle 19 having a silicon contact structure embedded in an edge of a multi-chip module. The contact structure is formed with a plug-receiving angle for deflecting multiple cantilevered plug contacts 17 into engagement with corresponding receptacle contacts 22. The silicon connector parts 19 have a thermal coefficient of expansion which matches that of silicon semiconductor and glass ceramic module 4 to maintain alignment over large temperature variations.
