Tailored Nonlinear Photonics: From Fundamental Concepts to Functional Structures

Thinking about quantum computing: why will it be based on light? Imagine absolutely tap-proof communication. Or think of measurements which will be much more precise than ever before … All these applications will be light based. Quantum technologies seem close to being ready for the market.

Photonics, which means light-based technologies, have strongly influenced our everyday life over the last decades. The invention of the laser and the development of optoelectronic semiconductor devices have led to the evolution of today’s information and communication infrastructure with a manifold of different applications in science and technology.

Our goal is to explore, develop and engineer future nonlinear photonics systems. We are using state-of-the-art technological capabilities for the exploration of new physics and devices based on tailored strong nonlinearities and genuine quantum effects.

A constantly changing world requires profound scientific and technological knowledge. And science does not need international or gender boundaries. Therefore, we need to work hard on excellent research in an inclusive environment. On September 19 and 20, 2023, young scientists of the CRC TRR 142 and guests were invited to present their current research as well as to reflect on career paths within sciences – and what it needs to overcome our…
