| 英文摘要 | PURPOSE:To improve the manufacturing yield of a collimator laser diode by rotating a laser element by a rotating mechanism to introduce a maximum light power incident to a fiber to accurately set a polarized surface to a specified position. CONSTITUTION:In order to assemble a collimator laser element, a guide pin 11 is matched to a cutout 12 of a cap 10, the cap 10 is fixed to a V-shaped groove holder 15, and the cap 10 is regulated by engaging the guide pin of a chuck with a hole formed at a stem 3 Then, a laser beam is output from a laser chip 21 by a laser diode driver 2 The beam is input through a lens 18 and a Glan-Thompson prism 17 to an optical fiber 16, and then measured by a power meter 22. If the power is smaller than a specified value, it exhibits that the polarized surface of the beam is not aligned. Accordingly, a rotating mechanism 20 is turned ON to regulate the cap 10, and when a predetermined power is obtained, the cap 10 is secured, for example, by a solder 33 to the stem 3 |
