The unidirectional scattering of high index metasurfaces is explored at Kerker condition using numerical simulations. We obtained the generalized first Kerker condition for an array of Silicon disks on a dielectric substrate that shows complete forward scattering using the multipole expansion method. We observe a significant Purcell enhancement for the quantum emitter embedded in the disk with emission wavelength overlapping with Kerker condition with a directional emission pattern. We also observed that this enhancement largely depends on the emitter's location and can be further engineered with the refractive index of disks.

Compact Optical components sensitive to incident wave-vector direction are essential in image-processing, wavefront-manipulation, and metrology such as LIDAR. Here we demonstrate a new class of metasurfaces which exhibit optical spectral features strongly correlated with incident illumination angle. The spectra of such metasurfaces feature sharp transmission dips centred around 800 nm when illuminated at oblique incidence, where the strength of the dip increases as incident angle increases remaining tightly confined within a 100 nm band. The metasurfaces are capable of accepting large incident angles (>30°) without the appearance of higher-order diffraction modes, while displaying dramatic transmission decreases (~80% reduction).

Photonic funnels, conical structures with hyperbolic cores, that have been recently demonstrated at mid-IR frequencies, provide a platform to avoid the diffraction limit and enable a smooth optical link between the nanoscale and microscale. Orbital angular momentum (OAM) of beams play important role in optical manipulation, microscopy, and potentially optical communications.. In this work we analyze theoretically the interaction structured light (light that has non-zero OAM) with photonic funnels. In particular, we study the effect of light confinement, facilitated through the geometric profile of the funnel, on spatial structure of the mode, and its local intensity.
