Description
Technical field
The present invention relates to optical communication technology field, especially a kind of optical fiber interface component of lock pin containing glass and preparation method thereof
And subcombination for optical.
Background technology
Optical fiber interface component (optical receptacle) be subcombination for optical (Optical Subassembly or
OSA important component), for receiving and positioning the joints of optical fibre.It is right in the Fiber Optical Communication System of high-end two-forty
The control of back-reflections light is extremely important.In order to prevent light from going back to influence optical fiber chain from the contact pin end face reflection of the joints of optical fibre
Road system, in optical fiber interface component, typically contains a ceramic insertion core or contact pin that glass lock pin comes with the joints of optical fibre
It is physically contacted, the refractive index of ceramic insertion core or glass lock pin is consistent with the fibre core in the contact pin of the joints of optical fibre so as to disappear
Except the contact pin end face reflection of the joints of optical fibre.In order to the reflected light for preventing the other end of ceramics or glass lock pin couples entering light
The other end of the contact pin of fiber connector, ceramics or glass lock pin needs to make an inclined-plane, generally 8 degree or 6 degree, so that
Prevent reflected light from along backtracking in case influence optical fiber link system.In particular：Plastics due to quality compared with
It is soft, it is easy to be scratched by contact pin, it is impossible to make contact surface to contact ferrule of optical fiber connector.
The optical fiber interface component that patent CN201859235U and CN202149947U are mentioned, is typically to contain ceramic insertion core
Traditional optical fiber interface component.This optical fiber interface component is typically made up of 4 to 5 parts, wherein containing high precision
Ceramic insertion core and ceramic sleeve, cause it into high cost, packaging technology is complicated, especially, dispensing and pressure in its assembling process
With action, automation mechanized operation is difficult to.
Patent US7387449B2 refer to a kind of optical fiber interface component containing glass lock pin, although it only has two parts
Composition, but its glass lock pin is complex-shaped, and it contains a planar end, an anchor ring and an inclined-plane, in order to be adapted to it
Metal shell elements a, in addition it is also necessary to chamfering.Because glass is hard brittle material, the production of this lock pin is got up, complex process, yield
It is low.
For subcombination for optical (OSA), when its tube core is light transmitting chip, this OSA is called TOSA
(transmitter Optical Subassembly, i.e. light launch sub-assembly).When tube core is light-receiving chip, we claim
This OSA is ROSA (Receiver Optical Subassembly, i.e. light-receiving sub-assembly).Certainly it is also other kinds of
OSA, such as BOSA (bi-directional single fiber component, it contains a light-emitting tube core and light-receiving tube core simultaneously), Triplexer is (single
Fine three-dimensional component, it contains a light-emitting tube core and two light-receiving tube cores simultaneously) etc..
One typical subcombination for optical OSA (see Fig. 1 a) is made up of following components：Metal base 400, tube core 500
(chip is launched or received to light), metal pipe cap 600, optical lens 700, optical fiber interface component 300.When OSA works, light
Fine interface module 300 can be inserted into the contact pin 200 (ferrule) of the joints of optical fibre.The optical fiber interface component being commonly used at present
300 mainly there is the barreled structure of internal diameter d by it, for stopping that the face 301 of ferrule of optical fiber connector constitutes.
As shown in Fig. 1 a, when tube core 500 is emission tube core, the light that it sends can be by the upper of optical lens (700)
Lower surface (701) and (702) focus at the lower surface 211 of fibre core 210 in ferrule of optical fiber connector, and then optical signal is in fibre core
In propagating to optical fiber link system in 210.
As shown in Fig. 1 a, when tube core 500 is to receive tube core, the incident ray propagated from fibre core 210 is in its contact pin
Sent at lower surface 211 and focused at tube core 500 by the upper and lower surface (701) of lens 700 and (702), by reception tube core
500 receive light, and optical signal is changed into electric signal.
, there is refractive index at three during the lightray propagation great changes have taken place in the subcombination for optical as shown in Fig. 1 a
Interface, is respectively face (211), face (701) and face (702).Generally at the interface of variations in refractive index, reflectivity can be by R=
(n1-n0) ^2/ (n1+n0) ^2 are calculated, and wherein n1 is refractive index such as fiber core 210 and the glass lens of optically denser medium material
700, n0 is the refractive index of optically thinner medium such as air, takes n1 ≈ 1.5, n0 ≈ 1.0, obtains Rf=4%, i.e., because these three interfaces are big
General a total of 12% energy is reflected, and this increases the insertion loss of subcombination for optical significantly.If these are reflected away
The light that backs towards be coupled into optical fiber link system, such as be easy to be reflected into optical fiber chain by the incident ray of face (211)
Road system, influence of the reflection light that these are backed towards to system includes：The centre wavelength of transmitting light source is caused to fluctuate；Cause transmitting
The light-intensity variation of light source；Increase optical fiber link system noise, permanently damage light source etc., and then influence whole light path system
Stabilization and bandwidth.
