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…
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…
Observation of multifractality of light in prime number arrays
Fabrizio Sgrignuoli, Sean Gorsky, Wesley Britton +3
Many natural patterns and shapes, such as meandering coastlines, clouds, or turbulent flows, exhibit a characteristic complexity mathematically described by fractal geometry. In re…
