    • A method of aligning an optical fiber to a laser diode obtains first light from the laser at a point designated as the center of a planar geometric shape. Data points are taken at the vertices of the shape, whereby a scan measures alignment quality at each of the vertices and the center. The scan begins by obtaining data at the center and moves to a vertex and the remaining vertices in either a clockwise or counterclockwise fashion. Alignment qualities are compared and the location of highest alignment quality is designated as a new center. The scan repeats until the location of the new center remains unchanged, whereby the new center becomes the point of alignment. Alternately, the scan iteration may repeat with increased resolution by reducing the size of the geometric shape and/or increasing the power from the laser until a point of alignment is found at highest resolution.
    • 将光纤对准激光二极管的方法在被指定为平面几何形状的中心的点处获得来自激光器的第一光。 在形状的顶点处获取数据点,从而扫描测量每个顶点和中心处的对准质量。 扫描从中心获取数据开始,并以顺时针或逆时针方式移动到顶点和剩余顶点。 对准质量进行比较,将最高校准质量的位置指定为新中心。 扫描重复,直到新中心的位置保持不变,从而新中心成为对准点。 或者,扫描迭代可以通过减小几何形状的尺寸和/或增加来自激光器的功率而以更高的分辨率发现对准点,从而以增加的分辨率重复。

    • A method of adjusting the attachment of an optical fiber to a laser diode chip within a butterfly package, or any equivalent package, identifies the location of the solder attachment on the optical fiber, thereby moving one or more high power lasers so that their respective beams are incident on the solder attachment. Then, with the application of high power laser pulses according to a predetermined pulse schedule, the solder attachment is heated so that the optical fiber may shift vertically therein. By using an internal or external monitoring means such as an optical power meter, a determination is made when the optical alignment has reached a desired threshold such as when it exceeds a desired optical power output. The pulse schedule may be performed multiple times until a substantially optimized coupling is achieved for the final package.
    • 调整光纤到蝶形封装或任何等效封装内的激光二极管芯片的连接的方法,识别光纤上焊料附着物的位置,从而移动一个或多个高功率激光器,使其各自的光束 发生在焊料附件上。 然后,通过根据预定的脉冲时间表应用高功率激光脉冲,加热焊料附着物,使得光纤可以在其中垂直移动。 通过使用诸如光功率计的内部或外部监视装置,当光学对准已经达到期望的阈值时,例如当其超过期望的光功率输出时,进行确定。 可以多次执行脉冲调度,直到为最终的封装实现基本上优化的耦合。
