Example Embodiment

[0018] In the high-port optical switch of the micromirror array type, the beam alignment of the fiber collimator array becomes a key process link in the fabrication of the device. After alignment, the optical signal emitted from any port of the input collimator array is required to pass through the After mirror reflection, it can be coupled into the exit collimator array. The optical alignment of the array mainly includes the following processes (such as Figure 4 shown):

[0019] 1. Make a collimator array like Figure 4 I or II in , so that the outgoing beams are equally spaced and parallel;

[0020] 2. Fix I, clamp A' in II in the fastening clip of the adjusting device, and carry out the alignment of A and A' ports in the two collimator arrays of collimator array I, II;

[0021] 3. Without changing the position of the collimator array I, rotate and adjust the collimator array II with the beam of A' as the axis, so that the insertion loss value of all ports is minimized. ...

Abstract

The invention discloses an optical fiber collimator array alignment regulating device, including slide blocks in three translational directions: top-bottom, left-right and front-back on the slip base, and also rotation regulating module composed by placing a small sleeve through the center and with fastening clamp of the optical fiber collimator in a big sleeve, the framework of the rotary module is installed with the first swing regulating module, there are the first and second swing regulating modules installed on the top of and at the bottom of the first connecting board, respectively, the two ends of the second connecting board are connected with the second swing regulating module and Z-direction translational slide block, respectively. It implements six resolved regulating freedoms by 6 independent regulating knobs. It can be widely applied to optical alignment regulation between optical fiber collimators and between their arrays in optical communication device packaging field.

Description

Technical field [0001] The invention relates to a device for adjusting optical elements, in particular to an alignment adjustment device for an optical fiber collimator array. Background technique [0002] Fiber collimator is an optical passive device, which is precisely positioned by pigtail and self-focusing lens. It can convert the transmitted light in the fiber into collimated light (parallel light), or couple parallel (approximately parallel) light from the outside into the fiber. In various optical communication devices, the optical path coupling using fiber collimator is a very common coupling method, and its coupling efficiency and adjustment speed have a direct impact on the insertion loss and packaging efficiency of the device. At present, five-dimensional optical adjustment frames are mostly used in China for optical alignment. [0003] Using a five-dimensional optical adjustment frame (such as Figure 5 Shown) for optical adjustment, the fiber collimator is pla...
