Abstract
The invention provides a package structure for a suspended optical branching device, which comprises a micromodule; the micromodule consists of a light-inlet end optical fiber tail fiber, a light-outlet end optical fiber array and a chip between the light-inlet end optical fiber tail fiber and the light-outlet end optical fiber array, wherein the micromodule is arranged in a steel pipe in parallel, two ends of the steel pipe are respectively provided with a plug, and optical fibers of the light-inlet end optical fiber tail fiber and the light-outlet end optical fiber array respectively extend out of the plugs; and the bottom of the chip is glued with the inner wall of the steel pipe by a double faced adhesive tape, and the tail of the light-outlet end optical fiber array which is far away from the chip is glued with the inner wall of the steel pipe by silica gel. The package structure is packed and fixed by the double faced adhesive tape and the silica gel, so that the badness of the device since the package glue flows to a coupling region can be avoided; and the mechanical reliability of the device can be improved due to the buffer action of the double faced adhesive tape and the silica gel.
Description
Technical field
The present invention relates to optical branching device encapsulation technology field, particularly a kind of encapsulating structure based on hanging type planar optical waveguide splitter micromodule.
Background technology
Optical branching device is claimed planar optical waveguide splitter again, is one of most important passive device in the optical fiber link.The hanging type planar optical waveguide splitter is the micromodule that a kind of intermediate chip portion exceeds fiber array substrate, and after encapsulation, its chip section and steel pipe inwall are not fitted.The encapsulation technology of present hanging type planar optical waveguide splitter adopts mostly micromodule directly is bonded in the steel pipe inwall with glue; As shown in Figure 1; The position of some glue 8 is positioned at the below of bright dipping end fiber array 3, near the coupling surface place of bright dipping end fiber array 3 with chip 2.The unfavorable factor of encapsulation is like this: the one, and glue 8 possibly flow to the coupling surface place during operation, and coupling glue produces stress, thereby causes device performance is caused a hidden trouble; The 2nd, because micromodule is directly to lean against steel pipe 4 inwalls, not cushion, when carrying out the Mechanical Reliability test, device comes off at steel pipe 4 inwalls easily, causes device bad easily, has influence on product and uses normally.
Summary of the invention
To the problems referred to above of existing hanging type planar optical waveguide splitter encapsulation technology, the applicant improves through research, and a kind of encapsulating structure that satisfies the hanging type optical branching device of device reliability is provided.
Technical scheme of the present invention is following:
A kind of encapsulating structure of hanging type optical branching device; Comprise the micromodule of forming by light inlet optical fiber pigtail, bright dipping end fiber array and the chip in the middle of both; Said micromodule is placed in parallel in the steel pipe; The two ends of steel pipe are equipped with plug, and said light inlet optical fiber pigtail, bright dipping end fiber array stretch out optical fiber respectively from plug; Said chip bottom is bonding through the inwall of double faced adhesive tape and steel pipe, and said bright dipping end fiber array is bonding through the inwall of silica gel and steel pipe away from the afterbody of chip.
Its further technical scheme is: said light inlet optical fiber pigtail, chip and bright dipping end fiber array are adhesively fixed through the UV solidified glue.
Useful technique effect of the present invention is:
The present invention uses the double faced adhesive tape fixed chip; Simultaneously in order to guarantee the gravity balance of device in steel pipe; Further use silica stationary bright dipping end fiber array, it is fixing to adopt double faced adhesive tape and silica gel to encapsulate, and has avoided device to flow to bad that the coupled zone causes because of packaging plastic water; Owing to the buffer action of double faced adhesive tape and silica gel, increased the Mechanical Reliability of device simultaneously.

Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 2; The present invention includes the hanging type planar optical waveguide splitter micromodule that the light inlet optical fiber pigtail 1 that is adhesively fixed by the UV solidified glue, bright dipping end fiber array 3 and middle chip 2 are formed, the horizontal level of its chip 2 is higher than the horizontal level of bright dipping end fiber array 3.Above-mentioned micromodule is placed in parallel in the steel pipe 4, and the two ends of steel pipe 4 are equipped with the plug 5 of plastic cement, the optical fiber that is used for fixing and protects light inlet optical fiber pigtail 1 and bright dipping end fiber array 3 to be stretched out.Chip 2 bottoms are stained with double faced adhesive tape 6, and the another side of double faced adhesive tape 6 and steel pipe 4 inwalls are adhesively fixed.Bright dipping end fiber array 3 has silica gel 7 away from the afterbody point of chip 2, is adhesively fixed through the inwall of silica gel 7 with steel pipe 4.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
