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…
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…
Design of infrared microspectrometers based on phase-modulated axilenses
Yuyao Chen, Wesley A. Britton, Luca Dal Negro
We design and characterize a novel axilens-based diffractive optics platform that flexibly combines efficient point focusing and grating selectivity and is compatible with scalable…
