Specific embodiment
Embodiment 1: as shown in Figure 1-2, a kind of m × N-shaped optical branching device visible ray trim component, including optical branching device 1, institute
The a port stating optical branching device 1 is connected with m root scattering optical fiber 2, and another port of optical branching device 1 is connected with n root scattered light
Fine 2, the core diameter of described scattering optical fiber 2 is 150 μm -170 μm.
Described optical branching device 1 is planar waveguide-type optical branching device, and the port of optical branching device is tapered transmission line, described taper
One end width that waveguide is connected with scattering optical fiber is equal to the diameter of scattering optical fiber, and one end that tapered transmission line is connected with scattering optical fiber
With diameter greater than tapered transmission line away from scattering optical fiber one end.Wherein, taper≤2.4 degree of described tapered transmission line.In this enforcement
In example, described taper is 2.4 degree.The length of described tapered transmission line is 3750um.The length of tapered transmission line adjusts with taper.
The rectangular waveguide that described tapered transmission line is 0.36% for refractivity；The substrate of described rectangular waveguide is quartz, sandwich layer
For mixing the silicon dioxide of ge, covering is the silicon dioxide mixing b, p, sandwich layer and substrate, the refractive index of covering be respectively 1.4502,
1.445 and 1.445, sandwich layer is 9 μm of section 9 μ m.Sandwich layer section is adjusted when actually used according to actual needs.
The scattering external laser instrument of optical fiber, as light source, the light that laser instrument sends is coupled into scattering optical fiber to laser instrument, passes through
Optical branching device is divided into some bundles.Because optical fiber is scattering optical fiber, when light passes through to scatter optical fiber, most of light can be dispersed into week
Confining space, the light being coupled into scattering optical fiber is scattered during transmission, so we have seen that scattering optical fiber is luminous.
In the present embodiment, in 170um, operation wavelength is in 405nm-1000nm for the core diameter of scattering optical fiber.Standard
The waveguide core layer of planar waveguide-type optical branching device (plc) is less than 10um.In Butt-coupling, scattering optical fiber and plc mould speckle are not
Join, coupling efficiency can be especially low.Want to obtain high coupling efficiency, need the waveguide of 170um*170um, but etching depth is
The sandwich layer of 170um is irrealizable.Show that tapered transmission line can improve coupling efficiency by experimental simulation data analysiss, therefore
Here line broadening is entered to plc port sandwich layer.Conical region width is identical with scattering fibre diameter, thickness and waveguide core layer thickness phase
With.So manufacture difficulty is little, and improves scattering optical fiber to the coupling efficiency of plc.
3d-bpm is utilized to be simulated the structure of the present embodiment, its analog result is as shown in Figure 3.As can be known from Fig. 3, bore
When shape length is enough, coupling efficiency ratio be not added with taper be doubled left and right.
In the present embodiment, 1 × N-shaped optical branching device visible ray trim component, n >=2, as shown in figure 5, in optical branching device one
Side inputs visible ray, and opposite side will export visible ray, and other optical fiber of homonymy are unaffected.So in left end as shown in Figure 5
After input light, all optical fiber of optical branching device right-hand member has light.If left side not input light, wanting all optical fiber has light, right-hand member
All optical fiber all must input light.
M × N-shaped optical branching device visible ray trim component, m >=2, n >=2, as shown in Figure 6.Defeated in optical branching device side
Enter visible ray, opposite side will export visible ray, other optical fiber of homonymy are unaffected.So shown in Fig. 6, optical branching device is right
One, end optical fiber inputs visible ray, and identical visible ray in all of optical fiber of left end.Another optical fiber of right-hand member inputs
Another kind of color visible, then the color observed in all optical fiber of left end changes.In left end input light, all optical fiber of right-hand member
Equally can output light.Want to change the color of fiberoptic visualization, the light of different colours can be inputted in different optical fiber, equally also may be used
Realized with changing light intensity.
Illustrated with instantiation below
One input port, two output ports, the structure of 1 × 2 type optical branching device visible ray trim component, as Fig. 7 institute
Show, after input port inputs the light of a color, be divided into the light of two bundle a colors after optical branching device, defeated by two output ports
Go out.In all optical fiber, now observe the light of a color.
Two inputs are in optical branching device side, an outfan, the knot of 1 × 2 type optical branching device visible ray trim component
Structure, as shown in figure 8, an input is inputted with the light of a color, inputs the light of b color, through optical branching to another input
Device synthesis is a branch of, is exported by outfan.There is the light of two kinds of colors in the scattering optical fiber being located due to outfan, so in outfan
Just the third color c different from color a and b of output.Here the principle of color blend is three primary color theory, for example a kind of
Have red in optical fiber, it is seen that the just yellow of scattering during the light of green two kinds of colors.With one principle of color television receiver, this
In color change be not that wavelength change causes, but visual effect.Can be by changing input a color of light or b color of light
Brightness or color are changing the color of c.
Change input light color and input port, an input is inputted with the light of a color, b color is inputted to outfan
Light, as shown in Figure 9.After optical branching device, there is the light of a and b color in the scattering optical fiber of an input, so observing
Color be c.Only has the light of b color in the scattering optical fiber of another input.There is a and b color in the scattering optical fiber of outfan
Light, so observe color be c.As long as so changing brightness or the color of a or b color, color c will change.
Three input ports, the structure of 1 × 2 type optical branching device visible ray trim component.As shown in Figure 10, can be by from three
Individual input port inputs the light a of three kinds of different colours, b, c.After optical branching device, have in the optical fiber at an input port place
The light of a and c color, the color observed in scattering optical fiber is d, and another input port has the light of b and c color, in scattering optical fiber
The color observed is e, and last input port has a, the light of tri- kinds of different colours of b, c, and the color observed in scattering optical fiber is
f.The change of a can lead to the change of e and f, and the change of b can lead to the change of d and f, and the change of c can lead to d, the change of e, f.
Embodiment 2: as shown in figure 4, a kind of m × N-shaped optical branching device visible ray trim component, including optical branching device 1, described

The core diameter of optical fiber is scattered in 170um, operation wavelength is in 405nm-1000nm in the present embodiment.Application is molten
Melt the method drawing cone, make optical branching device.Fused biconical taper optical branching device is to tie together two or multifiber, is then drawing
Fusion drawn on cone machine, fiber core layer is constantly close.Due to the hidden field that dies, light is coupled into another optical fiber, sandwich layer from an optical fiber
The nearlyer coupling efficiency of distance is higher.The change of simultaneous real-time monitoring splitting ratio, splitting ratio terminates fusion drawn, wherein after reaching requirement
One end retains an optical fiber, and remaining cuts as input, and the other end then makees multi-channel output.This method is in institute's path-splitting relatively
Low cost in the case of few, coupling efficiency is high.
