Description
Technical field
The utility model relates to fiber waveguide device, is the glass chip clamp that a kind of ion exchange method prepares waveguide, and these anchor clamps are mainly used in and utilize ion exchange method to prepare the extraction of glass substrate in the technological process of glass waveguide device.
Background technology
In recent years, along with developing rapidly of integrated optics technique, people are more and more deep to the research of optical waveguides, and the making of optical waveguides mainly is at Si, InP, LiNbO at present
3, finish on the substrate material such as glass, main preparation technology has plasma chemistry vapor deposition method, sputtering method, sol-gel processing, ion exchange method etc.Wherein utilize ion exchange method to prepare glass light waveguide device to have that manufacture craft glass waveguide device simple, with low cost, preparation has that transmission loss is low, specific refractory power and mould field distribution and optical fiber coupling well, be convenient to advantages such as integrated, in optical communication, optical sensor and other fields that need handle and control optical signal, wide application prospect is arranged.
The ultimate principle of utilizing ion exchange method to prepare glass waveguide is: glass substrate is immersed in the fused salt with certain temperature (as AgNO
3, KNO
3Deng), metallic cation is (as Na in the glass
+) with fused salt in metallic cation (as Ag
+Or K
+) exchange, the positively charged ion in the fused salt enters into glass, and the positively charged ion in the glass is displaced, thereby causes the change of exchange place specific refractory power, causes that the mechanism of refraction index changing mainly contains following three kinds:
(1) the radius difference of exchange ion causes that glass internal structure and molecular volume change;
(2) the electricdisplacement polarizability difference of exchange ion causes that the electricdisplacement polarizability changes;
(3) ion diffusion causes the variation of glass internal stress.
By the concentration of exchange ion and the time and the temperature of ion diffusion in the control fused salt, can control the change amount and the index distribution of specific refractory power, thereby prepare satisfactory glass waveguide device.To the good control of ion exchange process, as the homogeneity of fused salt, the homoeostasis of temperature etc. are the keys of the reliable and stable glass waveguide device of processability, then need once can carry out ion-exchange to the multi-disc glass substrate simultaneously for producing in batches simultaneously.Carried out ion-exchange is directly glass substrate to be put into the fused fused salt with tweezers in the past, with tweezers glass substrate is taken out after exchange finishes again, and this process must be opened the exchange furnace chamber, thereby can cause the variation of furnace temperature; When the multi-disc glass substrate was carried out ion-exchange simultaneously, each glass substrate overlaped easily in addition, caused exchange inhomogeneous, finally can influence the performance of glass waveguide device, was unfavorable for producing in batches.
Summary of the invention
The utility model provides a kind of glass chip clamp that ion exchange method prepares waveguide that is used at the problem that above ion exchange process exists, and this glass chip clamp should have simple in structure, and is easy to use and reliable, overcomes the shortcoming of above-mentioned prior art.In preparation waveguide process, needn't open the exchange furnace chamber, thereby can not cause the variation of furnace temperature; When the multi-disc glass substrate was carried out ion-exchange simultaneously, each glass substrate can be not overlapping, and ion-exchange is even, can produce in batches.
Technical solution of the present utility model is as follows:
A kind ofly be used for the glass chip clamp that ion exchange method prepares waveguide, it is by lifting rod, first clamp sheet, second clamp sheet and anchor clamps holder combine by a connection piece, described first clamp sheet, second clamp sheet respectively is a rectangular block, place two ends, the described web member left and right sides relative and parallel, be connected with described web member respectively, described anchor clamps holder is connected with the bottom surface of described web member, described lifting rod is connected with the end face of described web member, described first clamp sheet, the opposite face of second clamp sheet digs the groove of the relative one by one up/down perforation that plugs for glass substrate that is provided with two pairs or more, the end face of the glass substrate holder of described anchor clamps holder is prismatic or circular arc, described first clamp sheet, the bottom surface of second clamp sheet and anchor clamps holder is in same plane.
The cross section of described groove is rectangle or trilateral or semicircle.
Describedly be connected to fixedly connectedly, or dismountable bolt connects.When adopting bolt connecting mode, selects the web member connection of different length after, applicable to the glass substrate of different size.
The advantage of the utility model anchor clamps is:
1, the groove on first clamp sheet and second clamp sheet separates glass substrate, guarantees that fused salt can fully contact with glass substrate in ion exchange process.
2, glass substrate vertically inserts in the described groove of anchor clamps, after finishing, exchange mentions lifting rod, fused salt on the glass substrate flows down owing to action of gravity, can not remain in glass surface, glass substrate holder top cross section is trilateral or semicircle simultaneously, guarantee that fused salt flows down fully, also can not remain in the bottom of glass substrate.
3, these anchor clamps can be raised neatly, thereby after making glass substrate put into stove of exchanging, need not to open the exchange furnace chamber when carrying out preheating, exchange, annealing process, have guaranteed the stability of exchange temperature.
4, the length of first clamp sheet of the utility model anchor clamps and second clamp sheet can prolong as required, increase the right number of groove, the multi-disc glass substrate is carried out ion-exchange simultaneously, when particularly the lifting rod of these anchor clamps, clamp sheet, anchor clamps holder and web member adopt dismountable bolt connecting mode to make up, only need select the web member of different lengths for use, promptly be applicable to the glass substrate of different size, assembling is regulated flexibly, is suitable for producing in batches.
