Partial Symbol Detection Based Energy-Efficient Receiver for Short-Reach Optical Communication
… ISI from MSB transitions. This transforms the PAM-4 eye into a partially ISI-removed PAM-2 eye, reducing the number of comparators needed for a 1-tap PAM-4 DFE implementation from 12 to 4. Simulations show the equalizer can equalize up to 66% of ISI, enabling reliable operation at 112 Gb/s. The …

Pre-compensation of nonlinear distortion of a silicon microring modulator in short reach systems
… and without fiber transmission for a 28 Gbaud PAM-4 signal. The systematic simulation includes drive signal generation, electrical to optical conversion by the MRM model, fiber transmission, optical to electrical conversion and receiver side digital signal processing. Since the pre-compensation …

High Speed Optical Links Using CAP Modulation and Novel Equalisation Techniques
… equaliser, pulse amplitude modulation (PAM-4) scheme, and discrete multitone (DMT) scheme. CAP based data transmission of 112 Gb/s is achieved over 150 m OM4 fibre with this novel equaliser, while the conventional equaliser can only support over 1 m OM4 fibre and fails to recover the …

Machine learning approach for high speed link modeling and IBIS-AMI model generation
… to model pulse amplitude modulation 4 level (PAM-4) and non-return-to-zero (NRZ) system. Volterra kernels up to the third order can be accurately identified. The curse of dimensionality associated with Volterra series impedes the practical applications of the Volterra series. The number of …

Development of electrical and optical devices for next generation high-speed optical interconnects
… few milliampere bias range and enable >448-Gb/s PAM-4 operation but require tighter process control and microcavity-scaling insight. This thesis advances two fronts: first, a wafer-scale, OpenCV-based automated oxide-aperture measurement method that replaces manual ImageJ, enabling full-wafer …

Applications of Machine Learning in the Design and Optimization of Analog Integrated Circuits and Systems
… considers the optimization of a 64 Gbaud PAM-4 ADC-based optical receiver behavioural model, in which the previously proposed T-coil-enhanced ESD circuit optimization scheme is embedded. The third application uses reinforcement learning (RL) techniques to optimize critical analog IC …

Polarization multiplexed photonic integrated circuits for 100 Gbit/s and beyond
… In a system experiment using 28 GBaud PAM-4 signaling, error-free transmission of 100 Gbit/s is shown over 80 km of fiber. Finally, a fully integrated transmitter is demonstrated, comprising a distributed feedback (DFB) laser, a 45° PR and the aforementioned DP EAM. This is the first …
