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.
