Masterclass in Semiconductor Photonics
Abstract
Integrated Si photonics has sparked a significant ramp-up of investment in both academia and industry as a scalable, power-efficient, and eco-friendly solution. At the heart of this platform is the light source, which has been the focus of research extensively. This talk tries to tackle this issue from two perspectives: monolithic integration based on direct epitaxial growth and heterogeneous integration based on wafer bonding. In monolithic integration, significant improvements in III-V/Si epitaxy have pushed quantum dot technology to the frontiers of Si photonics. Meanwhile, a heterogeneous integration platform is showing very promising results, where a synergistic relationship between the III-V and Si gives rise to superior devices exceeding what is achievable with purely III-V devices. We will talk about the current state of application-driven on-chip silicon lasers. We expect to inspire further development in incorporating photonic integrated circuits with on-chip lasers for substantial performance gains, green solutions, and mass production.
