Silicon Photonics based Optical OFDM Solutions for Future Passive Optical Networks
In the context of Passive Optical Networks (PON), operators are looking for innovative solutions to increase aggregated data-rate, split-ratio and reach. Another requirement is that transceivers should be as low-cost as possible. The optical Orthogonal Frequency Division Multiplexing (OFDM) techniqu...

In the context of Passive Optical Networks (PON), operators are looking for innovative solutions to increase aggregated data-rate, split-ratio and reach. Another requirement is that transceivers should be as low-cost as possible. The optical Orthogonal Frequency Division Multiplexing (OFDM) technique can improve performance of the transmission in terms of data-rate and reach as compared to classical single-carrier On-Off Keying (OOK) modulation. At the same time, the silicon photonics technology can lower the cost per unit of the transceiver, due to its mass production and E/O integration capabilities. Optical OFDM has already shown its potential using commercially available optical components. However, its use with silicon photonics Directly-Modulated Lasers (DML) and modulators is more challenging. The objective of this work is to study the performance of OFDM -based solutions for future PON, using silicon photonics transmitters. For that purpose, a dedicated simulation platform is developed. The OFDM modem is implemented, as well as models of silicon photonic devices built during this thesis. These models are validated by characterizing physical components available for test.
