Integrated Photonics for Sensing, Imaging and Metrology – From Manufacturing to Application

Systems based on optical principles can provide new solutions for unmet needs in fields as versatile as medical diagnostics, point-of-care testing, environmental analytics, or production monitoring. They are particularly suitable for applications requiring non-invasiveness, high spatial or spectral resolution, robustness, or immunity against electric and magnetic fields. This comes along with a huge demand on miniaturization and compactness for their fabrication in order to realize precise measurement devices at higher volume and affordable costs. These trends have driven the development of manufacturing technologies for high-resolution structuring at micro- and nanoscales in the last decade.

In this webinar, Prof. Bernhard Roth will report on the fabrication and application of 2D and 3D optical structures with resolution beyond the diffraction limit reaching sub-100 nm feature size. For fabrication, Prof. Roth employs methods such as two-photon polymerization (2PP) or microscope projection photolithography (MPP). In the production chain, they also use UV nanoimprint lithography (UV-NIL) for replication at high throughput, especially for high-resolution and high-aspect-ratio features. Also, inline and offline metrology are required for monitoring and optimization of the process outcome. The structures produced are validated in applications such as distributed sensing, plasmonics or multiplexed analytics.
What You Will Learn:
• Different fabrication techniques for photonic devices
• Implementation of these devices in sensing and other applications

Who Should Attend:
• Masters and Ph.D. students
• Postdocs
• Professionals from research and the manufacturing industry
