JSII – High-Field THz Generation and Applications
Franz Kaertner, DESY, University of Hamburg, Germany and Peter Uhd Jepsen, Danish Technical University, Denmark
The symposium will highlight the most recent developments in exploration of strong-field interactions between light and matter in the THz range (loosely defined as 0.1 – 30 THz). The high interest and worldwide activity within this field is spurred by the possibility to generate ultrashort, tailored THz fields with strengths approaching that of the interatomic fields in matter, and probe the interaction on a timescale much shorter than the oscillation period of the fields. The understanding of the physics involved in such interactions is challenging, but the rewards for unlocking the potential of applications of such interactions are enormous: Computing at the clock frequency of a THz field without energy dissipation, quantum information processing, miniature accelerators, control of the behavior of complex molecules at the elementary level.

JSV – Flexible Photonics
Co-chairs: Giancarlo Righini, IFAC, Centro Fermi, Italy and Juejun Hu, Massachusetts Institute of Technology, USA
Conventional photonic devices are planar and rigid because of the substrates on which they are fabricated. However, the world is not flat and stiff: There are many applications that would benefit from soft devices and nonplanar geometries, such as interfacing with the soft, curvilinear, and dynamic surfaces of living organisms. This mismatch demands flexible and stretchable photonic devices that can be mechanically deformed without damage to their useful properties. This session will focus on latest advances in the field of flexible and stretchable photonic devices, address the scientific and technical challenges associated with their material choice, device engineering, as well as system integration, and highlight key applications enabled by the technology.
