Mode Integration Disorder Metamaterials: Electromagnetic Wave Manipulation From Arbitrary Coupled Modes to Single Mode

Laser &Photonics Reviews, EarlyView.
When a uniform field interacts with a complex medium, it becomes scattered into a nonuniform distribution. A mode‐integration metamaterial employs its intrinsic controlled disorder to coherently reorganize and integrate the scattered field components into a tailored modal output, establishing a new paradigm for programmable modal coupling and versatile

Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics

Laser &Photonics Reviews, EarlyView.
All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...

Reversible Thermal Tuning of High‐Q Non‐Local Lithium Niobate Metasurfaces

Laser &Photonics Reviews, EarlyView.
Introducing a polarization sensor using scattering in a short optical fiber and deep learning. The breakthrough lies in sparse sampling of the scattered light and single‐photon sensitivity. The all‐fiber sensor achieves unprecedented accuracy, speed, resolution, and stability.

512‐Fold Rotational Super‐Resolution via Four‐Photon High‐Dimensional Structured Light

Laser &Photonics Reviews, EarlyView.
A quantum rotation sensor that combines four photon states and high dimensional structured light ‐ characterized by a topological charge of 128 ‐ demonstrates a 512‐fold angular super‐resolution. ABSTRACT Structured light enhances quantum information processing by combining quantum states of light and shaped wavefronts.

Wavefront Control

, 2017
My research work falls under the theme of "High Angular Resolution", defined as the study and development of methods and instruments for approaching the limit of diffraction, in spite of dynamic aberrations. They focus on the measurement of the wavefront for adaptive optics and active optics and on the effects of optical propagation in the lower ...
