| Title | Design a Metalens for Visible Wavelength Imaging |
| Summary | Metalens are planar optical devices composed of subwavelength nanostructures that can manipulate light with unprecedented control. These lenses have the potential to replace traditional bulky optical components, enabling compact and high-performance imaging systems. In this project, we will design a high numerical aperture (NA) metalens using titanium dioxide (TiO₂) nanostructures. The metalens will be optimized to achieve diffraction-limited focusing comparable to state-of-the-art commercial objectives. The project will involve the use of finite-difference time-domain (FDTD) simulations to design and optimize the TiO₂ nanofins, which will act as half-waveplates to control the phase of incident light. The metalens will be designed to achieve high focusing efficiency (>80%). The final goal is to fabricate and characterize the metalens, showcasing its potential in compact microscopy, spectroscopy, and imaging systems. This project will provide students with hands-on experience in nanophotonics, optical design, and advanced simulation tools. Participants will gain a deep understanding of metasurfaces, Fourier optics, and the fabrication of nanoscale optical devices. The skills acquired will be highly relevant for careers in optical engineering, photonics, and emerging technologies in consumer electronics and biomedical imaging. |
