Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber arrays, in particular to an optical fiber array with positioning holes. Background Art

[0002] With the development of light sensing and fiber-optic communication, fiber arrays are used more and more widely. Fiber arrays are a kind of fiber optic device composed of multiple optical fibers arranged in parallel. Fiber arrays are usually connected with optical waveguide chips, silicon photonic integrated chips, micro-electromechanical systems and various integrated optical components. They are required to have high-precision fiber arrays with an accuracy of micrometer level.

[0003] Fiber arrays are important coupling components between optical devices and optical fibers because they can accurately position optical fibers. They are widely used in the manufacture of optical communication devices, such as planar optical waveguides, arrayed waveguide gratings, micro-electromechanical systems, and multi-channel optical modules.

[0004] The existing optical fiber alignment is generally to open a V-groove on the substrate. After the optical fiber is arranged in the V-groove, it is pressed by a pressure plate, then bonded with an adhesive, and finally the surface is polished. However, there is no restriction structure between the pressure plate and the substrate, and they are generally directly combined and bonded with an adhesive. This leads to the phenomenon that the pressure plate is easily misaligned when the pressure plate is used to press the optical fiber, affecting the connection accuracy between the pressure plate and the substrate.

[0007] When installing the first pressing plate, the first positioning block can be aligned with the first positioning groove and inserted to restrict the first pressing plate. Similarly, the second pressing plate can be aligned with the second positioning groove and inserted to restrict the second pressing plate.

[0008] Preferably, the first positioning hole and the first positioning block are both tapered, and before use, adhesive may be applied to the first positioning hole and the second positioning hole to improve the bonding effect.

[0009] Preferably, the second positioning hole and the second positioning block are rectangular, and the corners of the side of the second positioning block are provided with arc corners.

[0012] Preferably, a plurality of grooves cooperating with the optical fiber body are formed on the lower surface of the second pressing plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a first positioning hole and a second positioning hole on the substrate, and provides a first positioning block and a second positioning block that cooperate with each other.
