Multi-wavelength all-optical 3R regenerative apparatus based on magnetic control optical fiber parametric oscillator

Abstract

The invention discloses a multi-wavelength all-optical 3R regenerative apparatus based on a magnetic control optical fiber parametric oscillator. The multi-wavelength all-optical 3R regenerative apparatus comprises a first optical wave demultiplexing-multiplexing device and an optical annular cavity. The optical annular cavity comprises a coupler, magneto-optic high-nonlinearity optical fibers, an optical demultiplexer, a second optical wave demultiplexing-multiplexing device, an optical amplifier and an optical splitter, wherein the coupler, the magneto-optic high-nonlinearity optical fibers, the optical demultiplexer, the second optical wave demultiplexing-multiplexing device, the optical amplifier and the optical splitter are sequentially connected. Gains of the optical annular cavity are smaller than losses of the optical annular cavity. Compared with the prior art, the multi-wavelength all-optical 3R regenerative apparatus has the advantages that the problem that the system integration level is low due to the fact that a clock extracting unit and a nonlinear optical decision gate unit of a traditional all-optical 3R regenerative apparatus are independent is solved; meanwhile, the multi-wavelength all-optical 3R regenerative apparatus does not need to be synchronized with a reference clock, the problem that clocks can not be accurately synchronized is accordingly solved, the optical signal regenerative cost is accordingly reduced, and the multi-wavelength regenerative apparatus in a wave demultiplexing-multiplexing system is simplified.
