SYSTEM AND METHOD FOR CHROMATIC DISPERSION TOLERANT DIRECT OPTICAL DETECTION |
摘要 |
Embodiments are provided to improve direct detection for optical transmissions. In an embodiment, a method by a transmitter includes adjusting, using a nonlinear equalizer (NLE), a drive voltage for an optical modulator in accordance with a mapping between the drive voltage and an output of the optical modulator. The mapping is an inverse function of a nonlinear transfer function at the optical modulator between the output and to the drive voltage. The method further includes driving, using the adjusted drive voltage, the output of the optical modulator. The output is a single-side band (SSB) signal and is sufficiently linear with respect to the drive voltage for allowing direct detection at a receiver. |
