Pascal Del'Haye

Pascal Del'Haye is a Group Leader at the Max Planck Institute for the Science of Light (MPL) in Erlangen, Germany, where he heads the Microphotonics research group. His work focuses on advancing integrated photonics through innovative approaches to microresonator design, nonlinear optical phenomena, and frequency comb generation. With a strong publication record in high-impact journals, Del'Haye has established himself as a leading researcher in the field of microphotonics and nonlinear optics.

Dr. Del'Haye's research spans several key areas in modern photonics:

• Microresonator-based optical frequency combs and soliton physics
• Nonlinear optical phenomena including symmetry breaking and Kerr effects
• Advanced materials for integrated photonics, particularly silicon nitride platforms
• Novel designs for photonic integrated circuits using inverse design techniques
• Hybrid photonic systems combining multiple materials and nonlinear effects

His recent work (2023-2025) demonstrates a clear trend toward increasingly sophisticated integrated photonic systems that leverage multiple physical phenomena simultaneously. Del'Haye's group has pioneered approaches to control dispersion through segmented sidewall modulation, generate multiple comb states via cascaded Brillouin scattering, and combine different nonlinear effects in single devices through hybrid material platforms. This work has significant implications for telecommunications, sensing, quantum information processing, and precision metrology, with many publications highlighting the potential for CMOS-compatible implementations that could enable commercial applications and large-scale integration.

As a Group Leader at one of the world's premier photonics research institutions, Del'Haye supervises multiple researchers and students, fostering the next generation of photonics scientists. His work is supported by significant research funding that enables state-of-the-art experimental capabilities for nanofabrication and optical characterization, with recent publications indicating strong collaborations across multiple institutions and research groups.

The Microphotonics group operates advanced laboratories for photonic device fabrication and testing, with particular expertise in silicon nitride photonics, microresonator design, and frequency comb generation. The group collaborates extensively with other divisions at MPL and with international research teams to push the boundaries of integrated photonics technology, with recent work spanning from fundamental theoretical investigations of symmetry breaking to practical device implementations for optical switching and communication applications.
