title: PAM-N signaling by coupling modulation in a ring resonator.
abstract: A new method for an all-optical PAM modulation is presented. The method relies on coupling modulation of a ring resonator with an RF length much shorter than the previously proposed segmented MZI. The PAM modulator is optimized in terms of linearity both for the reverse and forward-biased cases. This modulator can operate for long haul communication with data rate only limited by the bandwidth of the MZI.
