Abstract
The present invention relates to a single-mode optical fiber and a multi-mode optical fiber which can be welded by alloys. The single-mode optical fiber and the multi-mode optical fiber are manufactured by technologically improving the existing optical fibers. The novel optical fibers not only keep the original specification and performance of optical fibers, but also increase the function of being welded by alloys. The novel optical fibers have the advantages of favorable welding soakage performance, high speed, sufficiently large tensile strength and stable and reliable welding quality. The novel optical fibers have wide purposes in the photoelectron field.
Description
Technical field: the present invention relates to a kind of technology at the surperficial dip-coating epoxide diluent of optical fiber nude.Described epoxide diluent is by epoxy material and dilution, and both mix composition in proportion.Dip-coating epoxide diluent on optical fiber nude surface, this optical fiber nude surface cure one deck epoxy molecular film and the coating that contains epoxy coating, then optical fiber nude surface energy is welded by a kind of solder.The soluble epoxy rete of term used herein " epoxy molecular film " is a molecular state, is meant the meaning as thin as a wafer.
Background technology: existing optoelectronic device all requires metallization coupling encapsulation, thereby optical fiber must metallize.Existing optical fiber metallization process is the specialized equipment sputter vaporization that adopts import, perhaps adopts the electroless plating mode, makes optical fiber nude surface, the rete of the gold that deposit one deck can weld, tantalum and so on.By this layer metal film, could implement the welding of optical fiber alloy.There are the following problems for this technology: 1, the import specialized equipment costs an arm and a leg, the technology more complicated; 2, the consumption precious materials is many, the production cost height; 3, optical fiber metallization position, fragility is big, and is disconnected easily.Owing to there are the problems referred to above, so once the someone studied the different trace element of interpolation in tin solder, be mixed with various scolders, carried out optical fiber alloy soldering test.This method, it is effective that the multimode optical fiber that epoxy acrylic acid ester coating was arranged is at that time carried out the alloy welding, can satisfy request for utilization basically, and single-mode fiber is carried out alloy welding weak effect, unsuccessful.[seeing also: " brazing metal test situation " report]
Summary of the invention: task of the present invention is the technology at the surperficial dip-coating epoxide diluent of optical fiber nude, and the coating that solidifies one deck epoxy molecular film and contain epoxy coating is gone up on the nude surface of this optical fiber, and the nude surface of optical fiber just can be welded by a kind of solder.Epoxide diluent is a kind of epoxy adhesive by epoxy material, dilution adopts absolute ethyl alcohol, first, the second that epoxy is gluing two components are with (2-10): 100 concentration ratio is dissolved in respectively in the absolute ethyl alcohol, and the lysate with first, second two components mixes composition by 1: 1 ratio again.The invention has the advantages that: the bare surface of optical fiber directly can be welded by a kind of solder, has saved the optical fiber metallization process, thereby has also just saved optical fiber metallization specialized equipment; Saved precious materials; Reduced the production cost of optoelectronic device.In addition, the method that provides the optical fiber all-metal to seal, developing optical fiber specific use.
Embodiment: the invention process is in optical fiber production process, increases together " in the formula skill of the surperficial dip-coating epoxide diluent of optical fiber nude ".Be embodiment now, the present invention is described further again with the preparation epoxide diluent.Current, best epoxy material is that DG-4 optical clear tackifier (epoxy binder modified) dilution adopts C
2H
5OH content is no less than 99.9%, and dust meets the absolute ethyl alcohol of ASTM " 0 " level, concrete compound method: take by weighing each 20 gram weight of epoxy adhesive first and second components, put into the absolute ethyl alcohol of the 500ml of glass bottle separately, cover bottle cap again, fully rock, make its dissolving.This bottled first, second components dissolved liquid can not precipitate, can long preservation.The epoxy dilution is made up of by amount mixing in 1: 1 lysate of first, second two components.Mixed epoxide diluent must leave standstill more than 72 hours, treated that oversaturated epoxy matter is solidified precipitation in the liquid, through filtering, obtain peace and quietly, face the epoxide diluent of Jie's state, use this epoxide diluent, dip-coating optical fiber nude surface, this optical fiber nude surface could cured epoxy molecule rete.
Dip-coating method is that epoxide diluent is placed on the optical fiber production line, and bare optical fiber was fully soaked.Being in operation simultaneously to be provided with one section temperature-controlled area, gives the epoxide diluent that is coated on the optical fiber dry rapidly, film-forming.Afterwards, by former explained hereafter optical fiber finished product.The single mode of this improvement, multimode and special optical fiber, its bare surface can both be welded by a kind of solder.Its welding wellability is good, and speed is fast, and enough big superior functions such as tensile strength are arranged.
