Hyperuniform scalar random fields for lensless, multispectral imaging systems
Yuyao Chen, Wesley A. Britton, Luca Dal Negro
We propose a novel framework for the systematic design of lensless imaging systems based on the hyperuniform random field solutions of nonlinear reaction-diffusion equations from p…
Optical rogue waves in multifractal photonic arrays
Fabrizio Sgrignuoli, Yuyao Chen, Sean Gorsky +2
Optical rogue waves are demonstrated in the far-field scattered radiation from photonic arrays designed according to the aperiodic distributions of prime elements in complex quadra…
Compact dual-band multi-focal diffractive lenses
Wesley A. Britton, Yuyao Chen, Fabrizio Sgrignuoli +1
We design, fabricate, and characterize multifunctional and compact diffractive microlenses with sub-wavelength thickness and the capability to simultaneously focus visible and near…
Phase-modulated axilenses as ultra-compact spectroscopic tools
Wesley A. Britton, Yuyao Chen, Fabrizio Sgrignuoli +1
We design and characterize phase-modulated, ultra-compact, silicon-based axilens devices that combine efficient point focusing and grating selectivity within scalable 4-level phase…
