Definitions

  • FIG. 4 is a photograph of chip we have designed containing both lasers a number of circuits (36 of them) in accordance with the invention. They have been tested in conjunction with post-detection amplifiers to boost signals to standard digital levels.
  • FIG. 5 is an eye diagram for the chip of FIG. 4 showing measurements of the variations or distortions in the optical signals. These circuits have been tested up to 2.5 Gb/s and have shown bit error rates (when using them to drive optical signals over more than 1 kilometer) of better than 10 "15 . We have further ascertained that the errors induced at this level are from laser noise issues and not due to fluctuations of the electronic base current.
