Multi-NA Metalens Array for Compact High-NA Microscopy
Alireza Khalilian, Jie Fan, Mehdi Sh. Yeganeh +2
We demonstrate a CMOS-compatible silicon-rich nitride metalens array for visible microscopy at 660 nm. Three co-planar elements provide numerical apertures of 0.54, 0.92, and 0.97,…

Polarization-Resolved Chlorophyll Imaging for Non-Invasive Plant Tissue Assessment Using a Silicon-Rich Nitride Metalens Array
Alireza Khalilian, Mehdi Sh. Yeganeh, Konstantin Tsoi +3
Polarization-sensitive imaging enhances contrast and reveals structural features in biological tissues that are often missed by intensity-based methods, but its adoption is limited…
