Description of the invention ο) [Technical field of the invention] The present invention relates to a program for cutting at least one optical fiber at one or more predetermined angles to form an angled or shaped end surface without grinding. Light. [Known technology] Optical fibers made of glass are often used in optical transmission systems and other optical systems. When using these single-mode or multi-mode fibers, the processing of the end faces of these fibers plays a decisive role. It is very important that the end face has a special standard surface to reduce the damping value as much as possible when transferring from one end of the fiber to the other or to the active original. It is also very important that the end face of the optical fiber can be manufactured at a predetermined angle and these angles are reliable and reproducible. Various mechanical methods are generally known for cutting optical fibers. In all methods, the optical fiber is basically fixed to a fixture, which has two holders to compensate each other, so that the correct angle can be ensured during the cutting operation, for example, using a diamond cutter. Methods for cutting by twisting the fiber or starting to break the fiber thereafter are also known. All of the above methods are expensive. In addition, the above methods can only be applied to parallel optical fibers of ribbon cables under certain conditions. It can be known from European patent 5 3 1, 2 2 5 that in order to cut the optical fiber, the optical fiber is fixed between the carriers of two holding and positioning devices. One of the carriers is deflected perpendicularly to the optical axis of the optical fiber and the use of a cutting blade is appropriate. Angle cut fiber. This method can be used for several optical fibers in parallel ribbon cables. [Invention Overview]

Description of the invention (2) The angle of the present invention or special purpose is the described feature, according to the present invention, at least one light is cut, and when the holding and output is short, it is manufactured with high precision. Polished. In other cases, there will be more or more moving lasers in this book. For example, the axis traversed by the fiber is included in the laser as a modification. The purpose is to provide a program shape that is accurately cut through a program. It has procedures such as other subsidiary items that provide favorable instructions for laser cutting of a fiber and optical fiber system supported by the yoke positioning device relative to the laser power pulse. A predetermined angle or shape, and one or more special optical fibers. Development of the first patent application. In multiple or multiple predetermined angle cutting and positioning devices, when the optical fiber is moved, the end face of the optical fiber can be melted by this end face without mechanically. The characteristic is that only a small amount of glass is melted during the cutting of the optical fiber . The design of the holding and positioning device of the invention is preferably that the device is a predetermined angle with respect to the laser, although the scope of the invention radiates a light beam. The angle of the beam passing through the optical fiber can be selected. In a simple structure, the single beam forms a flat end face, and the light leaves or enters the optical fiber at an angle relative to the axis. There are more paths in the device to form multiple faces. Or a wedge shape at the end of the curve

Description of the invention (3) Actually, the wedge shape is easily dulled by softening the surface tension of the optical fiber during cutting. This blunt wedge shape is used as a cylindrical The shape of the lens is very suitable for optically connecting an optical fiber and a laser with an elliptical beam. It is better to use a carbon dioxide (C 0 2) laser for cutting the laser beam of the optical fiber, although other lasers can also be used, for example: an excited laser (e X c i m e r 1 a s e r). Carbon dioxide lasers have proven to be particularly advantageous due to their high speed operation and cost benefits. During the cutting process, the fiber material is removed by carbon dioxide laser stripping, so the glass does not melt but sublimes. Carbon dioxide laser is more suitable for cutting fiber in pulse mode operation. The pulse energy is very high. The pulse is very short and has very steep edges. Therefore, the maximum pulse energy can be reached quickly. For example, the peak power of a better pulse is between about 0.1 to 100 watts and the pulse length is greater than 50 fs. The carbon dioxide mine has a peak power of 35 // S and a peak power of 600 watts. Radiation (wavelength 1 · 6 μm) can get very good results. Other lasers with wavelengths between 0.1 // m to 1.5 // m and 8.5 / zm to 10 // m can also be used. Since the previous mechanical system has a typical tolerance of +/− 0.5 // angle, the procedure according to the present invention can achieve a tolerance of less than 0.2 #angle. With the procedure of the present invention, not only individual fibers can be cut at an angle, but also ribbon cable fibers can be cut. Moreover, since the previous mechanical system can only perform low-level linear cutting, the program of the present invention can cut the fiber end face into any desired shape.

Description of the invention (5) The trimmer is positioned along the ay axis and then moved relative to the laser beam L s along the x axis. However, it is possible to move the optical fiber 3 relative to the laser beam by the spinner of the holding and positioning device along the ax axis or any other angle or combination of angles and curves. As shown in Figure 2, the end face 6 of the optical fiber 3 is manufactured at an angle relative to the fiber axis, and the inclination angle should be accurately reproduced. This purpose can be achieved through planned procedures. To carry out this procedure, the laser transmits short and high-energy pulses of laser light, so that the material of the optical fiber is sublimated. A very precise and high-quality optical fiber surface can be reached by laser cutting, so the extra polishing of the optical fiber surface, as required by general mechanical cutting procedures, is no longer needed. The end face 6 of the optical fiber cut by the laser is fully completed. As shown in Fig. 3, according to the program of the present invention, in addition to cutting individual optical fibers and completing the end face at the same time, the optical fibers 3 having the same end face quality can be arranged in parallel with each other and bundled at the same time (eg, ribbon cable) . For this purpose, the procedure for making the optical fibers 3 into a bundle is introduced into a positioning device 7 which ensures that the optical fibers 3 can be aligned parallel to each other. The vertical axis consistent with the optical fiber 3, for example: the X axis of the coordinate system. The positioning device 7 can be driven in the Y-axis direction, thereby ensuring that the optical fiber 3 is held in a parallel direction. In this embodiment, the laser beam L s is inclined by an angle α with respect to the Z axis, is focused on the optical fiber 3 via the lens 1 and operates in one of the foregoing short and high-energy pulse modes, and the optical fiber 3 passes through the aforementioned laser The light beam L s is thus cut off, and the end faces are completed simultaneously. As shown in Figure 4, the laser cutting of the present invention can be used to form a wedge-shaped light

Description of the invention (6) Fiber end face 4 1 This wedge shape is formed by passing the optical fiber through the laser beam at different angles. Because the surface tension of the optical fiber is softened during the laser stripping process, The wedge-shaped fiber end face 41 can be expected to be slightly blunt. The blunt wedge shape therefore presents a cylindrical lens 4 2 on the fiber end face. Such a shape is suitable for optically connecting an optical fiber and a thunder with an elliptical beam. Shoot. This procedure is beneficial to ensure that the optical fiber of the ribbon cable is cut with the same high quality end face and at the same angle.
