Metalens design for fiber-optic endoscope
On demand | Presented live 27 January 2024 
Abstract
We propose a workflow to design a metalens for a double-path fiber-optic endoscope application. The metalens is made of optical subwavelength scatterers (~106-108 meta-atoms) characterized individually with the Rigorous Coupled Wave Analysis (RCWA) method. They can collectively manipulate the phase, amplitude, and polarization of incident light. The response of the full metalens is reconstructed from the response of each individual unit cell according to a target phase profile optimized in ray-tracing optics software. Image acquisition with the full system is simulated in physics-based ray-tracing software with an ideal metalens and simulation-based fiber illumination in a 3D blood vessel environment.

Charly is a great engineer with a Master of Science in Optoelectronics Engineering and 15 plus years of experience in designing and simulating optics and photonics systems. He started his career at Coherent in laser photonics then worked in the San Francisco Bay area on LED lighting before joining Optis (now Ansys) in optical simulation software. He’s now Senior Product Manager for Lumerical, the photonics simulation software at Ansys. He listens to customers’ needs and edits the roadmap. He also focuses on developing synergies and workflows between photonics and optics at Ansys. His latest works have been related to OLED display optimization, coatings for Head-up display (HUD) combiners, diffraction gratings simulation for augmented reality (AR) glasses, and Metalens.
