Mirrors that demonstrate 98% reflectivity and withstand 10 kilowatts of focused continuous-wave laser light are created by nanoscale fabrication of single-crystal diamond. The work finds applications in medicine, defence, industry, and communications

High-power continuous-wave (CW) lasers are used in a variety of areas including industry, medicine, communications, and defense. Yet, conventional optics, which are based on multi-layer coatings, are damaged when illuminated by high-power CW laser li

Guided modes in nanometer thick anisotropic van der Waals materials are experimentally investigated and their refractive indices in visible wavelengths are extracted. Our method involves near-field scanning optical microscopy of waveguide (transverse

Vortex beams are characterized by a helical wavefront and a phase singularity point on the propagation axis that results in a doughnut-like intensity profile. These beams carry orbital angular momentum proportional to the number of intertwined helice

We demonstrate a novel characterization method of van-der-Waals' materials by performing near-field-microscopy of hexagonal-boron-nitride thin films on single-crystal silver. Beyond determining dispersion of optical modes, this technique also enables

2D phase gradients can be achieved from a 1D array of V-apertures. We exploit this degree of freedom, engineering asymmetric surface plasmon wakes whose wavefronts can be controlled arbitrarily and characterize them via near-field microscopy.

In this paper, we present new results on the controlled directional steering and focusing of surface plasmon polaritons (SPPs) via 1D and 2 D metagratings by changing the angle of incidence, the incident wavelength and polarization. These findings bu

We demonstrate that a metasurface can be designed that allows generating and controlling Surface Plasmons according to the illuminating light polarization state and wavelength. Plasmon focusing as well and generation and control of wakes will be disc

Surface plasmons polaritons (SPPs) are light-like waves confined to the interface between a metal and a dielectric. Excitation and control of these modes requires components such as couplers and lenses. We present the design of a new lens based on ho

In the Cherenkov effect a charged particle moving with a velocity faster than the phase velocity of light in the medium radiates light that forms a cone with a half angle determined by the ratio of the two speeds. In this paper, we show that by creat
