摘要： A method and system for storing and transmitting data using variable pulse symbology over a fiber optic or ultra wide band system. Data is stored in memory, accessed and transformed into an electronic or photonic pulse and/or space which has a variable duration, the duration corresponding to the bit of data to be transmitted. The duration of the pulse and/or space is selected from a list of predetermined durations, each corresponding to a different base 10 number. The pulses and spaces may both be used to represent data, or the spaces may be used for meta data. Variable duration pulses may also be used to store data on an optical storage medium or fiber optic cable.

摘要： An optical communication receiver, system, and method are disclosed. Optical communication may be implemented with less complicated and costly components yet use RZ-like signal formats. The method may also be adapted to provide communication with beneficial phase relationships among optical pulses. An originating signal has a plurality of pulses, each pulse defined by a leading edge and a falling edge. A plurality of first optical pulses are created and transmitted on an optical communication medium in which each first optical pulse corresponds to a leading edge of a corresponding pulse of the originating signal. A plurality of second optical pulses are created and transmitted on an optical communication medium in which each second optical pulse corresponds to a falling edge of a corresponding pulse of the originating signal.

摘要： Chromatic and polarization mode dispersion can be optically compensated with an All Optical Dispersion Compensator (AODC) of the present invention. The AODC compensates group delay in each polarization axis of an incoming dispersed signal pulse using multi-cavity Gires-Tournois resonators (MCGTR) and a feedback mechanism. Chromatic and polarization mode dispersion are compensated concurrently or independently.
