We show that Bragg gratings can be readily incorporated into metallic nano-lasers which exploit waveguides with semiconductor cores, via modulation of the waveguide width. This provides a simple way to implement laser wavelength control.

Optical imaging is the most widespread and versatile diagnostics and inspection tool in use today. While most of the current research in imaging is aimed at improving the spatial resolution to below the diffraction limit [1], there are numerous applications that demand improvement in temporal resolution [2]. Imagers with high temporal resolution are needed for studying fast phenomena such as shockwaves, chemical dynamics in living cells, neural activity, laser ablation, and microfluidics biochips. High-speed imaging is ever more important in microscopy because over the micrometer scale, even slow moving phenomena require high temporal resolution [2].

ZnO is one of the most attractive materials for optical applications in the visible and the near UV range, ranging from large-scale white-light illumination to miniaturized lasers for the near UV. Furthermore, the unique properties of the semiconductor ZnO are of high interest in the field where advanced optics meets the nanoarea. Because of strong exciton transitions near the electronic band gap and an electron-hole binding energy of 60 meV, the optical properties are dominated by strong lightmatter interaction, involving exciton polaritons. In macroscopic ZnO structures, light absorption and emission mediated by excitonpolaritons has been investigated in much detail. It was observed that exciton-photon coupling expressed as the longitudinal-transverse energy splitting is considerable stronger than in other II-VI or III-V semiconductors. In ZnO nanostructures, exciton-photon coupling can even be considerably enhanced due to photon confinement.

The sensitivity of electro-optic sampling of terahertz pulses may be doubled for beams of a finite size, since the terahertz field alters the probe beam diffraction and thus the Gouy phases of both polarisations differently.
