Specific embodiment
Fiber waveguide (optical waveguide) is the medium apparatus for guiding light wave to propagate wherein, also known as medium light wave
Lead.Slab dielectric optical waveguide is that the strip that a refractive index is n1 is produced in refractive index is for the matrix of n2, takes n1>N2, so as to
Light wave is confined to be propagated in strip.
Referring to figs. 1 to Fig. 6, that show the concrete structure of the preferred embodiment of the utility model.Below will specifically
The design feature of bright each element of the utility model, and be with Fig. 1 if being described to during direction (upper and lower, left and right, before and after)
Shown structure is that, with reference to description, but actually used direction of the present utility model is not limited thereto.
The utility model provides a kind of filled media type column fiber waveguide light guide plate, referring to Fig. 1, Fig. 4, light guide plate 1
Side forms incidence surface 11, and the upper surface of light guide plate 1 forms exiting surface 12, and the lower surface of light guide plate 1 forms reflective surface 13, guide-lighting
The exiting surface 12 of plate 1 is provided with site cylindrical recesses 14, light of the inside of site cylindrical recesses 14 using refractive index more than light guide plate 1
Electronic material filler 2 is filled, and photoelectron material filler 2 is combined with light guide plate 1 do not produce any chemical reaction, used as excellent
Choosing, the material of the light guide plate 1 uses PMMA materials, and refractive index is 1.3-1.7, and the material of the photoelectron material filler 2
