Abstract

Two optical transmitters are described, generating new modulation formats based on the simultaneous modulation of the amplitude and the phase of an optical signal. The proposed formats are compared to the traditional Non-Return-to-Zero (NRZ), showing improved tolerances to chromatic dispersion (CD), differential group delay (DGD) and to wavelength division multiplexing (WDM) channel spacing, and requiring electronics with halved bandwidth.
