  • Publication number: 20060088252
    Abstract: The invention relates to an arrangement for optically coupling an optical waveguide to an optical unit of an optical module. The optical module has a reference geometry, which defines a first axis of symmetry. There is an offset between the optical axis of the optical unit and the axis of symmetry of the reference geometry. The invention provides a coupling element which eliminates the offset. The coupling element has, for this purpose, a hole, which is delimited by an inner surface, the inner surface of the coupling element defining a second axis of symmetry. The first axis of symmetry and the second axis of symmetry extend parallel to one another and have an offset with respect to one another which is essentially the same as the offset between the optical axis of the optical unit and the first axis of symmetry of the reference geometry as regards direction and magnitude.

  • Patent number: 6853657
    Abstract: The invention relates to a method and device for determining the output power of a semiconductor laser diode being operated with a diode current. A defined measuring current, which is less than the threshold current of the semiconductor laser diode, is conducted in a conducting direction through the semiconductor laser diode. The forward voltage drop across the semiconductor laser diode is measured, and the temperature of the laser-active region of the semiconductor laser diode is determined from the measured forward voltage by using at least one calibration curve. The invention makes a simple and precise determination of the output power possible without requiring an additional measuring device, for example, a monitor diode.
