After three successful annual training events (2015-2017) with enthusiastic reactions, a fourth training is now organized in Santa Clara, CA. It covers all aspects needed for developing PICs such as a system level overview, a component tutorial, design & layout software, foundries, packaging, T&M, and business topics. During the hands-on training, participants will simulate, design, and layout PICs using a range of software tools. The training also addresses all key material systems (Si Photonics, InP-based, SiO2/Si3N4). The program has the full support of over 20 companies that span the complete photonic integration ecosystem, and includes several industry guest speakers as well as extensive networking opportunities, for example, in the form of facilitated group dinners.
