High frequency electro-optic measurement of strained silicon racetrack resonators

Abstract: The observation of the electro-optic effect in strained silicon waveguides has been considered as a direct manifestation of an induced χ(2) non-linearity in the material. In this work, we perform high frequency measurements on strained silicon racetrack resonators. Strain is controlled by a mechanical

Monolithically integrated waveguide-coupled silica microtoroids

Abstract: We report on the design and fabrication of a new type of microtoroid high-Q silica resonators monolithically coupled to on-chip silicon nanowire waveguides. In order to enable monolithic waveguide coupling, the microtoroid geometry is inverted such that the resonator

GeSn lasers for monolithic integration on Si

Abstract: Lasing under optical pumping is shown in suspended GeSn microdisks fabricated on a Ge virtual substrate with a lasing threshold below 1 mW at 20K. Intensive research has been carried out in the last years on novel materials for

High Speed WDM Interconnect Using Silicon Photonics Ring Modulators and Mode-Locked Laser

Abstract: We demonstrate an 8 by 14 Gbps compatible WDM link based on a single-section semiconductor mode-locked laser, silicon photonics resonant ring modulators and joint channel reamplification with a semiconductor optical amplifier operated in the linear regime. Individual channels reach
