Abstract
When sampled simultaneously by a set of synchronized high intensity beams, a device consisting of a sequence of interlinked Nonlinear Sampling-Gates, through which a signal beam propagates, generates a replica of the intensity of the signal beam, during the interaction period. The device may be implemented optically or electrically as an ultra-high speed parallel receiver and when sampled by a femtolaser may be used to read a data train in parallel and thus at almost in real time. The device may also be used to stretch, compress, multiplex, demultiplex, read headers and help switch data trains optically in communication networks.

A sequence of interconnected, 2 input (A and B), 2 output (C and D), Gi sampling gates, (i=1 . . . n) defined by the table
- 3 A B C D 0 0 0 0 0 1 0 0 1 0 0 1 1 1 1 0
- for sampling an electromagnetic wave, wherein the output Di (i=1 . . . n−1) of each sampling gate, after being delayed by Ti=(Δti+ti)(i=1 . . . n−1), where (Δti) is the time delay within the sampling gate and ti is the delay between the output Di of a sampling gate (i) and the input Ai+1 of the successive gate G(i+1), is fed to the input Ai+1 (i=1 . . . n) of the following sampling gate, and wherein the sampling inputs Bi (i=1 . . . n) are applied to all the interconnected (n) sampling gates simultaneously for a sampling period τi, synchronized with the electromagnetic wave fed at input Ai, leading to the simultaneous appearance of all the outputs Ci for the same period τi, after a time delay (δτi) the length of which depends on the nature of the interaction of the electromagnetic wave with the matter of which the sampling gate (i) is made,
