ABSTRACT:
The present invention provides an all optical system for generating high rate modulated signals including: a generator for generating a first periodic signal at a first rate; an optical chopping device arranged to receive the first periodic signal for producing a second periodic signal having pulses that are narrower than the pulses of the first signal; a splitting device for receiving and splitting the second periodic signal into multiple images of the second periodic signal propagating along multiple optical paths, the multiple optical paths including optical modulators for modulating the images of the second periodic signal at a first rate to produce modulated signals; an interleaving device for receiving and interleaving the modulated signals to produce a stream of modulated signal having a second ratewhich is higher than the first rate. In another version the present invention provides an optical rate increasing device, and in yet another version the present invention provides a system for interleaving multiple information channels into a high rate data stream.
