Hybrid Integration in Photonics, challenges of incorporating III-V and 2D dichalcogenides into Silicon Photonics

Abstract

In this talk, we will present the development of semiconductor lasers obtained by the incorporation of III-V epitaxial material to a silicon photonics platform. Also, the incorporation of transition metal dichalcogenides for saturable absorption in this platform will be demonstrated. We will show how both technologies are of great importance for the creation of new functional and flexible photonic systems.
