  • Method and arrangement for controlling modulated lasers
    Patent number: 6647040
    Abstract: A method and an arrangement for controlling modulated lasers are provided, in which an input signal of a laser is modulated by a pilot signal. The combined signal that is emitted is then utilized to control the laser. In order to substantially prevent individual spectral lines of the input signal from affecting the pilot signal, a pilot signal is selected with a frequency spectrum that is spread substantially uniformly in the spectral range of the input signal. Versions of this method are also known by the term “spread spectrum modulation”.
    Type: Grant
