It is refined et al. to apply superlattice submodeling analysis dispersion characteristics of the high refractive index solid core Bragg optical fiber near 1.55 mum wavelengths, it begs for
The relationship of the core diameter of Bragg optical fiber, covering period, filling rate and waveguide dispersion is discussed.In September, 2006, Beijing University of Post & Telecommunication
Liu little Yi, Zhang Fangdi have delivered the polarization characteristic of a high refractive index ellipse core Bragg optical fiber in Acta Optica, with full vector
The finite Element Method Study polarization characteristic of high refractive index ellipse core Bragg optical fiber discusses Bragg optical fiber as polarization maintaining optical fibre
Possibility.So far, do not find solid core Bragg optical fiber near 1.064 mum wavelengths transmission characteristic and its it is super it is continuous aspect
Related patents information.
From above-mentioned investigation it is found that predominantly staying in 1.55 mum wavelengths to the research of high refractive index solid core Bragg optical fiber at present
In terms of neighbouring dispersion and the numerical simulation of transmission characteristic.The biggish pump light source of power, which is more advantageous to, obtains high power, broad band
Super continuous spectrums output, and in terms of laser selection, near infrared band at present, 1.064 μm be Nd:YAG laser feature
Wavelength, Nd:YAG laser are a kind of solid state lasers that can produce high-power ultrashort pulse of classics, but to this type optical fiber
Dispersion and its hardly seen report of super continuation property near 1.064 μm of windows, for the super company of output high-power, broad band
Continuous spectrum, it is necessary to study dispersion characteristics and nonlinear characteristic of the optical fiber near 1.064 μm.Currently, with the rank of sulphur based material
Jump single mode optical fiber and photonic crystal fiber can generate in infrared super continuous spectrums, but due to the dispersion characteristics of single mode optical fiber
Not easy-regulating hardly results in color dispersion plainness characteristic, although and photonic crystal fiber can be by adjusting its dispersion of its structure regulating
Characteristic, but photonic crystals optical fiber structure complexity is not easy to prepare in the actual process, therefore is difficult to the reality of output super continuous spectrums
In the research of border.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of colors of infrared super continuous spectrums in generation

Bandwidth reaches the flat ultra-wide super continuous spectrums of 300nm or more.Therefore in order to generate flat ultra-wide super continuous spectrums, it is necessary to obtain most flat
Dispersion characteristics.The present invention designs a kind of high refractive index solid core Bragg optical fiber structure of dispersion flattene, and fibre-optical dispersion is due to mould
Dependence of the propagation constant β of formula to wavelength, the dispersion with optical fiber structure relating to parameters are waveguide dispersion.Influence Bragg optical fiber color
The factor for dissipating characteristic mainly has optical fiber core diameter, lattice period, low, high-index material thickness ratio, refringence and lattice
The period number of plies, and with fiber core radius, lattice period, the increase of low, high-index material thickness ratio, dispersion curve is to long wave
Length direction is mobile, and dispersion curve flatness declines, and it is bent to be located at the flat dispersion near 1.064 μm for zero dispersion point in order to obtain
Line approach is exactly to change the value of each impact factor respectively, selects dispersion curve at 1.064 μm nearby flattest one group
Structural parameters.It is obtained by COMSOL and MATLAB Study on Numerical Simulation, to keep dispersion more flat, it is necessary to suitably reduction fibre core
Radius, lattice period and low, high-index material thickness ratio, and in order to increase nonlinear effect, suitably increase again high and low
The refringence of refraction materials.
By the above technical solution of the present invention, compared with existing, significant beneficial effect is:
Solid core Bragg optical fiber in the present invention passes through preferably using high refractive index, high non-linearity tellurate glass as fibre core, gram
It takes each structural parameters and 1.064 μm of windows is obtained nearby very by adjusting its structural parameters to the uncertainty of dispersive influence
Flat dispersion characteristics can be used for generating broadening to red in 2.5 μm using its high non-linearity characteristic and color dispersion plainness characteristic
Outer flat super continuous spectrums output.
