Some Developments in Silicon photonics for On-Chip Optical 

Pedro Rojo Romeo, Ecole Centrale de Lyon, Ecully, France

  

The diversification of materials and functions on a Silicon platform is a key issue to enable further progress in micro-optoelectronic integrated devices. The monolithic heterogeneous integration of new materials on silicon, and more generally the combination on the same wafer of materials having different physic and properties is an important challenge.

In the photonic field, integration of III-V semiconductors and functional oxides Si platforms would open tremendous perspectives. In particular, ferroelectric oxides such as BaTiO3 (BTO) and Pb(Zr,Ti)O3 (PZT) present optical properties liable to add flexibility, agility and re-configurability in integrated photonic systems, while InP based III-V materials open the path to integrated laser sources on silicon around 1.5 µm for on-chip optical interconnections.

This seminar presents concepts and results on integrated sources on SOI platform and functional oxide based modulators, for silicon photonics and optical interconnection, during the last decade at INL.
