Title: Silicon on-chip laser sources: from fundamental research to real-world applications
Abstract: The silicon photonics platform has rapidly gained maturity over the last few years. High-performance passive filters such as high-Q ring resonators and well-optimized detectors and modulators were demonstrated. Integrating lasers directly on silicon, however, remains as a fundamental challenge for silicon photonics. In this talk, a recent breakthrough of integrating high quality III-V semiconductor materials directly on silicon is introduced as a viable path to tackle this obstacle. On the other hand, being anticipated as a new photonics platform, more and more system level demonstrations based on silicon photonics for various applications can be found in literature. As an example, this talk introduces an on-going work on silicon integrated mode-locked lasers that could enable various applications, such as microwave photonics, nonlinear photonics, biophotonics, etc.
