Silicon Photonics (SiPh) based PICs will replace bulky photonic modules with discrete components such as lasers, wavelength filters and photodetectors and condense them into one chip. These PICs can be used in applications ranging from gas sensors, LIDARs and medical imaging devices to energy-efficient optical links for data-centers and quantum computers. At VTT, we pattern optical waveguides into a 3 μm thick silicon-on-insulator (SOI) layer. Light remains extremely well-confined inside the micron-scale Si waveguides leading to a unique combination of low propagation losses (~0.1 dB/cm), small polarization dependency, dense integration and ultra-broadband operation. By combining rib and strip-shaped waveguides it is possible to achieve single-mode (SM) operation over an ultra-wide wavelength range (like 1.2–3 μm) while pushing bend radii down to a few micrometers. Our latest highlights include 40 GHz photodetectors and 1xN wavelength multiplexers with about ~ 1 dB loss. We offer the low-cost option to join our multi-project wafer (MPW) runs, as well as dedicated processing runs and strategic partnerships for product development at all stages of the development phase – conceptualizing, feasibility studies, design support, prototyping, dedicated runs, testing, assembly, and packaging. PDK is readily available with mature process modules. Commercializing your Si photonic products by obtaining contract manufacturing services is also an option. You can also benefit from our extensive network of R&D partners around the world for subcontracting, hybrid integration of III-V optoelectronics, and funding opportunities.
Srivathsa Bhat received his M.Sc. degree in photonics from SSS University in 2008, and his M.Tech. degree in solid state technology from Indian Institute of Technology, Madras in 2010. Between 2010-2015, he pursued his doctoral degree under Meint Smit in the Photonic Integration group at Eindhoven University of Technology where he focused on hybrid integration of InP membrane lasers on Silicon. Later in 2015, he joined 7 Pennies Consulting where he holds the position of a senior business analyst focusing on forming clusters and organizing workshops and trainings on photonic integration targeting the North American markets. In 2017, he joined VTT’s integrated optics group and his current focus is on the design and fabrication of photonic chips. He is a member of OSA
