Abstract
A method and apparatus for modulating a beam from a laser with an electro-absorption modulator, and determining the optical power of the beam by measuring a back current produced by the electro-absorption modulator. The apparatus comprises an electro-absorption modulator and a back current detector. The electro-absorption modulator receives an electronic digital signal from an electro-absorption driver. The electro-absorption modulator modulates the beam of the laser according to the electronic digital signal. While modulating the beam, the electro-absorption modulator produces a back current. This back current is proportional to the optical power of the beam. The back current detector measures the back current to determine the optical power of the beam.
