Electrical interconnects present a bottleneck in data centers due to their bulkiness, limited bandwidth and high heat dissipation. Optical interconnects present a potent alterna-tive to meet the ever-growing demand for massive and fast data transmission. Although they are already omnipresent in data centers today, they have not replaced electronics on all levels yet. As Silicon Photonics matures, it offers a cost effective solution that can be co-integrated with electronics at the chip and package level due to its CMOS compatibility. This work aims at realizing a Wavelength Division Multiplexed (WDM) transceiver for use in DataCom as a mid-board optical module using a Mode Locked Laser (MLL) as light source and resonant devices for modulation and filtering. The first part of the project included the design and optimization of a resonant ring modulator meeting the band-width requirements, while achieving maximum efficiency. In the second part, the full transceiver was built and measured. In parallel, a model of the transceiver was developed to predict the link budget.
