Description
A kind of process for producing welded-connecting type single-mode optical-fibre coupler and device thereof relate to the fiber optic passive device manufacturing technology.
Making single-mode optical-fibre coupler with welding process only is the hi-tech that grows up the nearly several years.Known manufacturing process is just shelled into naked fibre with the single-mode fiber middle part, a pair of or several naked fibres are crossed as hinge shape, put into the heating of specific high temperature temperature, when treating naked fine fusion it is drawn into taper, control molten condition and stretching tapering can obtain single-mode optical-fibre coupler.Yet, because the small geometrical size of single mode waveguide fiber structure is the complicacy of optically-coupled between the optical fiber in addition, make existing manufacture method have certain blindness, add thermal temperature field or change the automatic control that the expense expensive investments realizes fused biconical taper even update, this has also only improved operation repeatability, so far can not improve the finished product yield, particularly ultralow insertion loss high-quality product yield.
The present invention's purpose aim to provide a kind of just can online in real time when in manufacture process ground detect these the just process for producing welded-connecting type single-mode optical-fibre coupler and devices thereof of the relevant light characteristic between processed single-mode fiber and optically-coupled state.
Basic design of the present invention has been to break through the product manufacturing and product detects the general concept of making a clear distinction between good and evil.Even when single-mode fiber is being processed into coupling mechanism, still can inject light signal to its arbitrary fiber end face, yet detect all optical fiber breech face change in optical signal, and this variation has also reflected this instantaneous optically-coupled characteristic in the manufacture process just truly in real time.In view of the above, method provided by the present invention and device thereof are made up of five aspects such as optical signal source, light signal injection, hydrogen-oxygen micro flames, fused biconical taper, detection record.Optical signal source (1) (9) provides certain optical signals, that is: the wavelengthtunable high strength monochromatic light pulse of wavelength coverage 0.5 μ～1.6 μ, and its monochromatic value should be with just the coupling mechanism operation wavelength processed be identical.This certain optical signals is injected into just at processed arbitrary single-mode fiber end face by injecting (2); Simultaneously, hydrogen-oxygen micro flames (7) (8) carries out the heating of indirect type high temperature to optical fiber, carries out fused biconical taper by (4) and makes coupling mechanism; Detection record (5) (6) then detects and record the change in optical signal of all processed optical fiber tail ends all the time.The arbitrary end face that promptly the invention is characterized in the single-mode fiber of being processed by hydrogen-oxygen micro flames (7) (8) and fused biconical taper (4) is injected the certain optical signals that (2) are injected to be provided by optical signal source (1) (9) by light signal, and in coupling mechanism manufacturing overall process, detection record (5) (6) is carried out detection record to the change in optical signal of all processed optical fiber tail ends all the time.
Accompanying drawing and description of drawings:
Fig. 1. represent systematic schematic diagram of the present invention.
The light source of optical signal source (1), light signal inject the hydrogen-oxygen gas path pipe (8) of (2), processed single-mode fiber (3), fused biconical taper (4), optical signal detector (5), registering instrument (6), micro flames hydrogen-oxygen steel and source of the gas (7), PE or PVC, the grating monochromator (9) of optical signal source.
Fig. 2. represent that optical signal source of the present invention and light beam go into arrangements of components figure.
Optical signal source frame (10), light source power adjustable transformer (11), light source heat radiation cover (12), emergent light condenser lens (13), accurate little (14), monochromatic light pulse concentration lens (15), the optical modulation sheet (16) transferred of five dimensions.
Fig. 3. represent fused biconical taper of the present invention and detection record arrangements of components figure.
Available plasticine single-mode fiber chuck (17) (24) that processed single-mode fiber is fixed thereon, micro flames lamp holder (18), xy registering instrument (19), signal amplifier (20), the fused biconical taper frame (21) formed by φ 3 and φ 10 double-layer stainless steel concentric tubes, can drive the Fibre cartridge for optical connector motion and implement the high-quality suprasil sleeve pipe (25) that draws the optical fiber of awl to draw awl motor (22), driving belt (23), be used as the φ 3.5 that heats indirectly.
Most preferred embodiment:
The light source of optical signal source need only adopt general low-voltage, high-current high-intensity incandescent lamps bubble, can as light source power, change the output voltage control intensity of light of (11) with adjustable transformer (11) as light source as the projector bulb.Light is focused on by optical focusing lens (13), the white light that is modulated into about 100 hertz through optical modulation sheet (16) enters grating monochromator (9), emergent light after the beam split is that wavelength coverage is the wavelength-tunable high strength monochromatic light pulse of 0.5 μ～1.6 μ, should be identical with the operation wavelength of processed coupling mechanism as for the monochrome value.With this monochromatic light pulse is the certain optical signals that detects usefulness, be injected into any one that has into folded up in the processed single-mode fiber (3) at little (14) center of the accurate accent of five dimensions after 10/0.25 optical lens (15) focuses on, the light signal injection efficiency is guaranteed by meticulous adjusting (14).When light signal is delivered to fused biconical taper (4) along (3), when promptly being coupled the processing district, light signal will produce various variations, and outputing to receiving tube (5) from every velamen work sheet mode fiber breech face, light signal changes little electric signal into and amplifies through low frequency microvolt amplifier (20) and enter into xy registering instrument (19) record.Meanwhile, promptly when light signal was injected into (3), the processing of coupling mechanism was also carried out.Hydrogen-oxygen micro flames lamp holder (18) carries out indirect heating by quartz socket tube (25) to single-mode fiber, so that thermal field evenly and do not have oxyhydrogen flame and stain, treat that drawing awl motor (22) when the softening i.e. startup of optical fiber makes Fibre cartridge for optical connector (17) (24) drive (3) do to move along fiber length by the transmission of (23), promptly draws awl.So far, welded-connecting type single-mode optical-fibre coupler can obtain.
The present invention collects manufacturing and is detected on new method and the new equipment thereof of one owing to providing a kind of, is worth so have in actual applications great technology, must produce positive remarkable result. Put into practice already proved invention and effectively optimized technological parameter, greatly improved reliability of technology. The product yield particularly high-performance high-quality coupler yield of low insertion loss (＜=0.5dB), ultralow insertion loss (＜=0.1dB) is multiplied; The product manufacturing cycle shortens half or more, and cost descends. In addition, the present invention also can divert from one use to another in other similar fiber optic passive device manufacturings.
