Project: Nonlinear modeling of silicon photonics electro-optic modulators

Acronym: nodeSipher
Main Objective: The main objectives of project nodeSipher are:
1. Set up a customized probe station suitable for both high frequency RF (up to 20 GHz) and optical characterization of devices combining RF and optical stages;
2. From experimental data, build a nonlinear model of the MZM with two inputs: the voltages applied to the phase shifters, and two outputs, the I and Q components of the modulated optical signals;
3. Use the nonlinear model of the MZM to implement nonlinear pre-distortion algorithms, one tailored for intensity modulated signals, and another suitable for amplitude and phase modulated signals;
4. Estimate the performance gains of the nonlinear pre-distortion algorithms for:
a. IMDD modulation formats, such as PAM and DMT;
b. Coherent modulation formats, such as QAM and OFDM;
5. Assess the gains provided by the nonlinear pre-distortion in realistic scenarios of:
a. NGPON access networks carrying 2.5 Gb/s 4PAM and QPSK signals;
b. Datacenter interconnections carrying up to 40 Gb/s signals using M-PAM and M-QAM.
