This presentation gives an overview of the micron-scale silicon waveguide platform at VTT. This includes low-loss and polarization independent waveguides, components and photonic integrated circuits. Photonic integrated circuits (PICs) are primarily based on 3 µm thick silicon-on-insulator (SOI) waveguides, while some work is also done with 12 µm thick SOI waveguides. Latest results are provided about power-efficient switches and phase modulators, polarization splitters and rotators, and monolithic Ge photodiodes (up to 40 GHz). A path towards monolithically integrated, broadband isolators and high-speed modulators is shown. Some examples of III-V hybrid integration on SOI and optical I/O coupling are also given. This includes up-reflecting mirrors, which support wafer-level testing and packaging, as well as broadband anti-reflection coatings. Main focus will be on concepts that support dual-polarization and high-power operation over the continuous wavelength range from 1.2 to 1.8 µm, and also mid-infrared operation up to 5 µm wavelength.
Dr. Timo Aalto has worked at VTT since 1997 with the primary research focus on silicon photonics. He received his M.Sc. and D.Sc. degrees in optoelectronics technology from the Helsinki University of Technology in 1998 and 2004, respectively. He leads the Photonics Integration team that is the key user of VTT's clean room facilities in Espoo (Micronova) and Oulu. He has ~80 peer-reviewed journal and conference publications. He has reviewed EU projects, journal articles and theses, and written one book chapter. He has coordinated several large projects funded by EU, the European space agency, national funding organizations and industry.
