Erwin Bente

Erwin Bente is an Associate Professor at the Department of Electrical Engineering, Eindhoven University of Technology (TU/e), specializing in laser-based photonic integrated circuits. He leads research within the Photonic Integration group and contributes to the Center for Care & Cure Technology Eindhoven.

• MSc in Physics (1984) and PhD in Laser Spectroscopy (1989) from Vrije Universiteit Amsterdam
• Industrial researcher (1988–1994) and team leader at University of Strathclyde (1996–2001)
• European chair of IEEE International Semiconductor Laser Conference technical program committee

His research focuses on semiconductor laser design, photonic integration, and optical sensing. Key areas include:

• Laser dynamics and feedback robustness
• High-resolution beamforming with grating antennas
• Frequency stabilization techniques (e.g., Pound-Drever-Hall)
• Extending wavelength ranges for medical and sensing applications
• On-chip calibration of optical phased arrays
• Monolithic integration of tunable lasers and amplifiers

Recent publications (2024–2025) demonstrate advancements in:

• Indium phosphide (InP) photonic circuits for sensing
• Beam steering with sub-degree resolution
• Frequency comb stabilization for metrology
• Hybrid silicon nitride metalens fabrication
• On-chip calibration algorithms for optical phased arrays
• Applications in optical coherence tomography and LiDAR
