Abstract
The present invention relates to a method for connecting optical-fiber miniature devices. In a connected miniature device, the connecting end surface of one connector is stuck into a circular ring of soft glue by the soft glue. After the soft glue is solidified, the connecting end surface is in contact with the connecting surface of the other connector. The light penetrating surface is positioned in the circular ring of soft glue, and finally, UV glue or epoxy glue is added to a groove composed of the two connectors and the circular ring of soft glue to be used for fixation. A product obtained with the method ensures expedite light paths, improves sticking strength, ameliorates product quality, and has wide application ranges.
Description
Affiliated technical field
The present invention relates to a kind of coupling method of optical fibre micro devices, particularly a kind of dense wave division multiplexer is the coupling method of DWDM device.
Background technology
DWDM (dense wave division multiplexer) device accounts for more and more important position in optical-fibre communications, diaphragm type DWDM device package is occupied the core of DWDM device.
At present, a kind of main flow scheme is to adopt double optical fiber head and 0.25Pitch (cycle) GRIN Lens to make collimating apparatus in the membrane type DWDM device packaging technique scheme, its coupling method as shown in Figure 1, two optical fiber kapillaries 108 are formed optical fiber head 103 with optical fiber cable 101 and 102,105 is GRIN Lens, and 107 is DWDM diaphragm or WDM (wavelength division multiplexer) diaphragm; Diaphragm 107 is close to GRIN Lens 105 end faces, GRIN Lens and diaphragm bond with glue 106 by the side, regulate GRIN Lens 105 and double optical fiber head 103 positions, make and enter light from optical fiber cable 101 and arrive diaphragm 107 back other wavelength light except that transmission peak wavelength and reflex to double optical fiber head 103 by diaphragm 107, in the inner fiber line 102, the gap is tens μ m magnitudes between GRIN Lens 105 and the double optical fiber head 103.Adopt UV glue 104 end face adhesive methods between GRIN Lens 105 and the double optical fiber head 103.This method advantage is that GRIN Lens and double optical fiber head cohesive strength are very firm, its distinct disadvantage is that fiber end face adds glue in the optical fiber head, because the single-mode fiber bright dipping accounts for only several microns, UV glue passes through high power laser light for a long time, glue-line may destroy, thereby influence product quality, and the UV glue-line also there is problem of aging, also influences its caking ability.Another kind method is as shown in Figure 2, and 201,202 is optical fiber cable, and 203 is double optical fiber head, is made up of with optical fiber cable 201,202 two optical fiber kapillaries 208, and 204 is UV glue, and 205 is GRIN Lens, and 206 is glue, and 207 is WDM or DWDM diaphragm, the same Fig. 1 of principle of work.Here different is adhesive method between GRIN Lens 205 and the double optical fiber head 203, the method that employing is solidified with UV glue 204 at GRIN Lens 205 and double optical fiber head 203 cylindrical sides, be that GRIN Lens 205 does not have glue with the logical light face of double optical fiber head, because by the glue bond of outer fiber face, it solves end face does not have the glue problem, but its cohesive strength greatly descends, and anti-drop safety coefficient is being reduction.
Summary of the invention
The objective of the invention is to: a kind of coupling method of novel optical fibre micro devices is provided, and making it is not influencing coupled self performance, and guarantees to improve linking intensity and damage resistance under the prerequisite unimpeded in the light path.
The present invention adopts following method to achieve these goals: in two coupled micro devices, coupled end face with one of them connector, be bonded to the flexible glue circle with flexible glue, make logical light face in circle, connection end face with another connector contacts with this circle is soft again, adds the stickup glue bond and fix in flexible glue circle groove peripheral and that form between two coupled.
This method needs the microclearance to regulate the connection of optical element applicable to any optical fiber, and connecting of double optical fiber head and GRIN Lens or connecting of optical fiber head and optical element.
Adopt as above structure, utilize flexible glue to form O-ring seal in the double optical fiber head outer ring, realize that the logical light face of optical fiber does not have glue, isolate optical fiber fiber core outer ring optics end face and solidify glue, and flexible glue circle thickness can be slightly larger than two connector gaps, so the gap is fixed with UV glue after can adjusting as required again.The flexible glue circle can guarantee that also logical light face does not have glue, thereby has guaranteed product quality, makes light path unblocked, and cohesive strength improves greatly simultaneously.

Embodiment
Present embodiment is that two optical fiber connect with the best that GRIN Lens forms collimating apparatus, as shown in Figure 3,301,302 is optical fiber cable, 303 is two optical fiber kapillaries, 308 is double optical fiber head, 304 is the flexible glue circle, is to be bonded to tens micron thickness circles with flexible glue in double optical fiber head 308 optical fiber outer rings, and it is little greater than gap between the double optical fiber head 308 of making the 0.25Pitch collimating apparatus and the GRIN Lens 305 that its flexible glue solidifies back thickness.When making double-fiber collimator (the same Fig. 1 of its structural principle), the 304 little deformation of flexible glue circle as shown in Figure 4, form fiber cores and outer space state that cage ring is cut apart double optical fiber head 308.As shown in Figure 6, when double optical fiber head 308 and GRIN Lens 305 relative positions are adjusted to best collimating apparatus, be that double optical fiber head 308 1 optical fiber cables 301 incident lights are except that transmitted light, other wavelength light are reflected when entering double optical fiber head 308 another optical fiber cables 302, between GRIN Lens 305 and double optical fiber head 308 cylinders, penetrate into adhesive glue 309, the groove that flexible glue circle 304 and double optical fiber head 308 and GRIN Lens 305 are formed, make and remove flexible glue circle 304 outer field grooves 310 and all be full of adhesive glue 309, adhesive glue 309 can be UV glue or epoxy glue, adhesive glue 309 solidify to form the double-fiber collimator finished product, this moment is because optical fiber head 308 and the most of directly bonding of GRIN Lens 305 end faces, its cohesive strength greatly strengthens, and logical light face 410 no glue.
Another kind embodies on the bonding of the microclearance that can be used for optical fiber cable and other optical element, and it is expressed as follows:
The first step adopts ultra-fine hollow cylinder kapillary, as external diameter 200 μ m, and internal diameter 126 μ m, micro-flexible glue on the end of hollow cylinder bonding solidifies as shown in Figure 8.801 is kapillary, and 804 is flexible glue.
Second step, in kapillary, insert the port optical fiber of plated film, fiber end face is little to be lower than flexible glue 804 end faces, and curing optical fiber line 801 and kapillary 802 positions form a specialty optical fiber head like this, and diameter can be very little.
The 3rd step, specialty optical fiber head and optical device, as waveguide device position relative adjustment, flexible glue forms seal between optical fiber head and optical device, and the little deformation of flexible glue makes optical fiber head and optical device that leeway, certain adjusting gap be arranged afterwards.After optical fiber head and optical device relative position are determined, coat adhesive glue in the outside and solidify.This has guaranteed that logical light face does not have glue and shared space is small, and the favourable integrated optical device that is applied to of technology connects.
