Meta-optical processors for broadband complex-field image operations
Linzhi Yu, Jesse Pietila, Haobijam J. Singh +2
All-optical image processing provides a fast and energy-efficient alternative to conventional electronic systems by directly manipulating optical wavefronts. However, metasurface-b…
Phase-shifting structured illumination with polarization-encoded metasurface
Linzhi Yu, Jesse Pietila, Haobijam Johnson Singh +1
Phase-shifting structured illumination is a powerful technique used across diverse imaging modalities, including 3D surface measurement, quantitative phase imaging, and super-resol…
Meta-operators for all-optical image processing
Linzhi Yu, Haobijam J. Singh, Jesse Pietila +1
All-optical image processing offers a high-speed, energy-efficient alternative to conventional electronic systems by leveraging the wave nature of light for parallel computation. H…
Epsilon-near-zero nanoparticles
Ibrahim Issah, Jesse Pietila, Tommi Kujala +3
In this work, we propose epsilon-near-zero (ENZ) nanoparticles formed of metal and dielectric bilayers and employ the effective medium approach for multilayered nanospheres to stud…
