Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with specific embodiments.

[0025] refer to figure 1 , a device based on Peregrine solitons using saturable absorbers to generate high-quality pulses, including: Peregrine soliton generators 1, saturable absorbers (SA) 2, erbium-doped fiber amplifiers (EDFA) 3, standard single-mode fiber (SMF) 4 , an isolator (ISO)5, a polarization controller (PC)6, a high dynamic range optical spectrum analyzer (OSA)7 with 2.5GHz resolution, and an ultrafast optical sampling oscilloscope (OSO)8 with sub-picosecond resolution. The Peregrine soliton obtained by the Peregrine soliton generator 1 is input into the saturable absorber (SA) 2, and the background wave of the (PS) is eliminated by using the saturable absorber, and then the Peregrine soliton of eliminating the background wave is sent into the erbium-doped fiber amplifier ( In EDFA)3, after amplification, the power of the Peregrine soliton reaches 2P 0 (P0 ...

Abstract

The invention discloses a device and method for generating high-quality pulse trains based on Peregrine solitons, comprising: a Peregrine soliton generator (1), a saturable absorber (2), an erbium-doped fiber amplifier (3), a first single mode fiber (4), isolator (5), polarization controller (6), spectrum analyzer (7) and optical sampling oscilloscope (8); the beneficial effects of the present invention are: (1) utilize saturable absorber to eliminate Peregrine The background wave of the soliton; (2) amplified by an erbium-doped fiber amplifier and transmitted in a single-mode fiber to obtain a breathing pulse for long-distance stable transmission, which suppresses the splitting of the Peregrine soliton in the fiber; (3) realizes The method is relatively simple, and provides a new method for generating light pulses.

Description

technical field [0001] The present invention relates to the field of fiber optic solitons, in particular to a device and method for generating high-quality pulses based on Peregrine solitons using saturable absorbers Background technique [0002] The Peregrine soliton theory to be studied here was proposed by Peregrine, but it has not been discovered at first. It wasn't until 2007 that Solli observed extreme soliton pulses. These rare optical events have the hallmark phenomenological characteristics of sea monster waves, their peak power is very large and seemingly unpredictable, they follow L-shaped statistics, occur in nonlinear media, and have broadband and temporal characteristics compared with typical events The steepness of this light wave becomes an optical strange wave. There are many views on the physical mechanism of optical strange waves, one of which is described by Peregrine solitons. Peregrine solitons are soliton pulses on a planar background that are local...
