| 英文摘要 | The invention provides a method for efficiently performing the alignment work of a laser diode chip with an optical fiber. A laser diode chip is faced to a coupling end face of a lensed fiber. According to algorisms stored inside an algorism storage part, X, Y and Z stages move the lensed fiber for alignment. The lensed fiber takes in laser light as it is moved in the optical axis direction (Z-axis direction) of the laser light from the laser diode chip. The lensed fiber is moved in the Z-axis direction by every movement, a half of a wavelength of the laser light, on the basis of the reference position thereof. Every time at the step moving, a light power of the laser light incident into the lensed fiber is measured. A position where the measured value becomes the maximum or a neighboring position thereof is defined as the optimum position of the optical fiber in the Z-axis direction. After rough alignment by whirl alignment, the optimum position of the optical fiber on the XY plane is determined by microalignment according to a five-point alignment method. |
