  • Method for the reciprocal positioning of an optical fiber and a semiconductor laser and a positioning apparatus using this method
    Patent number: 4728187
    Abstract: The invention provides a method and apparatus for aligning an optical fiber and a semiconductor laser. The positions of the laser and of the fiber are located with respect to a fixed reference system, which is an optical detector which identifies the transverse light emission of the laser. With the laser position, the fiber is advanced so that it "flies over" the laser: the fiber then modulates the light received by the detector of the reference system. The fiber is moved back by a known amount and is moved by scanning in the plane transversal to the emissive axis of the laser, until a second optical detector, placed at the other end of the fiber, receives a maximum of light transmitted by the fiber.
