  • Patent number: 7068936
    Abstract: Methods and apparatus for providing a time slot switch which performs switching in the optical domain without the need for O-E-O conversion is described. The time slot switching device of the present invention may be part of a large switching device capable of performing switching and other function on WDM, TDM and WDM signals which are time division multiplexed. An optical time slot switch implemented using a time slot demultiplexer, optical cross-connect, variable delay lines and time slot multiplexer are described. Frequency conversion may be performed on a per time slot basis in cases where time slot signals are switched between lines using different wavelengths. Wave division demultiplexers and multiplexers can be added to the basic time slot switch to provide support for WDM switching and switching of TDM signals which are transmitted using wave division multiplexing.

  • Publication number: 20040245216
    Abstract: In fabricating an apparatus such as a silicon device or an optical device initially a wafer having a plurality of dies is formed. These dies are then separated into individual dies and the individual dies are formed into encapsulated devices having input and/or output leads. The dies are separated by a means that is not based on crystallographic plane cleavage. Additionally the boundary along which the separation is performed is not a linear path. By employing non-linear paths that are not constrained by crystallographic planes, device yield per wafer is substantially improved particularly for dies having non-linear boundaries. In one embodiment the dies are separated using an alternating dry etching and polymer deposition technique.
