title: Beyond amplitude-only detection for digital coherent system using directly modulated laser.
abstract: We report the first experiment of digital coherent detection of directly modulated signals that utilizes both phase and amplitude of the signals. A novel algorithm is proposed to take advantage of simultaneous detection of both phase and amplitude of the modulated signal. Using our proposed scheme, the experiment shows 6-dB improvement over the amplitude-only detection scheme.
