Dielectric metasurfaces have different Q-factor and light localisation requirements for sensing and imaging. Here, the authors present a dielectric metasurface, supporting two optical modes with sharp Fano resonances for high Q-factors and strong spa

Light trapping has now been recognized as an essential element of highly efficient solar cells. A large number of sophisticated nanostructures have been developed and optically characterized, many of which have been aimed at thin-film silicon technol

Chromatic aberration is a major challenge faced by metalenses. Current methods to achieve broadband achromatic operation in metalenses usually suffer from limited size, numerical aperture, and working bandwidth due to the finite group delay of meta-a

Metalenses are nanostructured surfaces with great potential for delivering miniaturized and integrated optical systems. A key property of metalenses is that, by using a double layer configuration, or doublet, they can achieve both diffraction-limited

A double surface is required to mitigate aberrations of metalenses. Doublets are still not well understood, and designs rely on numerical optimization. We unveil the physical principles and limitations of doublets, leading to analytical designs.

We developed an analytical model to estimate the impacts of optical losses on the performance of photonic resonant sensors. We find that the resonance amplitude plays a significant, albeit underestimated, role on the performance.

We introduce a form-birefringent single layer metalens encoding two phase profiles on the same surface to correct spherical and off-axis aberrations allowing the switching from high resolution to wide field of view operation.

The interest in high quality factor (high-Q) resonances in metasurfaces has been rekindled with the rise of the bound states in the continuum (BIC) paradigm, which describes resonances with apparently limitlessly high quality-factors (Q-factors). The
