To generate high energy electron beams, conventional accelerators use radio frequency waves to accelerate charged particles to relativistic speeds. However, the accelerating electric field produced is limited to a few tens of megavolts per metre, mai

In this thesis we study the interaction of light with the environment at the nanoscale. Fluorescent emitters are ideal candidates to probe this interaction because their emission properties strongly depend on the surrounding environment. The emitters

The mid-infrared region of the electromagnetic spectrum is very attractive for various applications, including safety and defence. However, most of the mature sources do not meet every need regarding efficiency, compactness and wavelength range. The

When a defect is introduced into a phononic crystal, states localized at the defect appear in the band gaps. They decay rapidly far away from the defect. Therefore, it is possible to localize and guide wave propagation by designing defects in the per
