Abstract
A fiber array is capable of ensuring an accurate position of a fiber in an array. The fiber array comprises two precision flat glass substrates with projection edges and fibers. The fibers to be positioned are compactly limited between the two glass substrates in the vertical direction and in the transverse direction, so that the fibers draw close to each other and the fibers and the glass substrates draw close to each other. Therefore, accurate positioning of the fiber array is achieved.
Description
Affiliated technical field
The utility model relates to a kind of fiber array.Especially can guarantee the exact position of optical fiber in array.
Background technology
At present, known fiber array is that bare fibre is fixed in accurate glass V-type groove.Its principle is to rely on accurate " V-type groove " to limit and the array position of fixed fiber.So the degree of accuracy of fiber array is decided by the precision of V-type groove completely.And conventional optical fiber spacing is 250 microns.
Summary of the invention
Depend on the deficiency of V-type groove in order to overcome the precision of existing fiber array, the utility model provides a kind of fiber array, not only can be more the position of accurate positioning optical waveguides, and without using accurate V-type groove.
The technical scheme in the invention for solving the technical problem is: adopt upper and lower two smooth planar glass substrates, one side of glass plate is less than with a thickness raised brim that a fibre diameter is greater than its radius, utilize the precision of bare fibre self, optical fiber is arranged in smooth plane closely, pressed fiber on upper and lower, left and right both direction, make between optical fiber very close to each other, then cementing fixing.The horizontal centre distance of adjacent fiber is exactly the diameter value of an optical fiber like this, is generally 125 microns, and distance between two optical fiber of the optical fiber in interval is exactly 250 microns.We only need select the optical fiber needing after cementing fixing, and remaining optical fiber has just participated in location, and its part that exceeds glass substrate can be removed.The number of fibers that the size of planar glass substrate can be arranged is as required determined.
Same principle, for the requirement of different fiber core distances, can also select the optical fiber of different-diameter to adjust.
The invention has the beneficial effects as follows: planar glass substrate is easily prepared, and the precision of burnishing surface is more easily guaranteed.In array, the deviation of all fiber optic hubs position is only subject to the impact of the precision of optical fiber own, so precision is more guaranteed, and the number of fibers of arranging is more, and it is just more obvious to the superiority of accuracy guarantee.Method is easy, and effect stability is reliable.
Accompanying drawing explanation
That the utility model is described in further detail in conjunction with the accompanying drawings and embodiments below.
The structural representation that a fiber core distance of accompanying drawing 1～3 use is equal to 4 fiber arrays of 125 microns of fibre diameter values further illustrates principle of the present utility model.
Embodiment
As shown in accompanying drawing 1～3, all with a protruding edge, its thickness is slightly less than the diameter of optical fiber to two glass substrates up and down of preparation (in figure 2., 3. indication) as required, but guarantees to be greater than the radius of optical fiber.Diagram 1 signal: 4 diameters that the first step is arranged needs are that the bare fibre (in figure 1. indication) of 125 microns is positioned between two glass substrates (in figure 2., 3.); Diagram 2 signals: second step closes up two substrates up and down and is compacted to optical fiber and is fitly arranged in up and down on the supporting plane of glass substrate; Diagram 3 signals: the 3rd step is closed up two substrate left and right horizontal directions to be compacted to optical fiber close proximity, then cementing fixing.Realize thus optical fiber accurately arranged together by the fiber core distance of 125 microns, obtain the fiber array needing.
Claims (3)
1. the fiber array that can guarantee the exact position of optical fiber in array, is characterized in that: adopt upper and lower two smooth planar glass substrates with raised brim that optical fiber is closely aligned into accurate array.
2. fiber array according to claim 1, is characterized in that: use two smooth planar glass substrates, one side of glass plate is less than with a thickness raised brim that a fibre diameter is greater than its radius.
3. fiber array according to claim 1, it is characterized in that: optical fiber is closely arranged in smooth base plan, compacted on upper and lower, left and right both direction, make between optical fiber and optical fiber and substrate between very close to each other, the then cementing formation fiber array that is fixed together.
