Diffraction-free natural optical skyrmions and their subwavelength confinement around vortices
Nilo Mata-Cervera, Deepak K. Sharma, Ramon Paniagua-Dominguez +2
Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has bee…
Neural network enabled wide field-of-view imaging with hyperbolic metalenses
Joel Yeo, Deepak K. Sharma, Saurabh Srivastava +8
The ultrathin form factor of metalenses makes them highly appealing for novel sensing and imaging applications. Amongst the various phase profiles, the hyperbolic metalens stands o…
Dynamic Control of Momentum-Polarization Photoluminescence States with Liquid-Crystal-tuned Nanocavities
Chengkun Dong, Matthew R. Chua, Rasna Maruthiyodan Veetil +5
Dynamic control of light, and in particular beam steering, is pivotal in various optical applications, including telecommunications, LiDAR, and biomedical imaging. Traditional appr…
Long-range quantum emitter interactions mediated by a non-local metasurface: Application to qubit-qubit entanglement
Hannah Riley, Emmanuel Lassalle, Diego Romero Abujetas +3
Scalable quantum technologies demand long-range interactions between many distant quantum emitters (QEs). We introduce non-local metasurfaces supporting bound-states-in-the-continu…
EigenCWD: a spatially-varying deconvolution algorithm for single metalens imaging
Joel Yeo, Duane Loh, Ramon Paniagua-Dominguez +1
The miniaturization of optics through the use of two-dimensional metalenses has enabled novel applications in imaging. To date, single-lens imaging remains the most common configur…
Optical Skyrmions of Vortex Darkness
Nilo Mata-Cervera, Deepak K. Sharma, Yijie Shen +2
We disclose the existence of a type of optical skyrmion, Gauss-Stokes (GS) skyrmions, that is naturally present in an optical vortex around its phase singularity. Contrary to previ…
Wavelength Control of Perovskite Metasurface Lasing via Electrical Microheaters
Tim Meiler, Yutao Wang, Saurabh Srivastava +4
Perovskites have recently brought significant advances to active nanophotonics, offering a unique combination of gain and phase-change properties for tunable light-emitting devices…
