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…
Aperiodic bandgap structures for enhanced quantum two-photon sources
Luca Dal Negro, Yuyao Chen, Sean Gorsky +1
In this paper we propose a novel approach to enhance the efficiency of the two-photon spontaneous emission process that is driven by the multifractal optical mode density of photon…
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…
Refractory doped titanium nitride nanoscale field emitters
Alberto Nardi, Marco Turchetti, Wesley A. Britton +5
Refractory materials exhibit high damage tolerance, which is attractive for the creation of nanoscale field-emission electronics and optoelectronics applications that require opera…
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…
