We report on the experimental realization of an optical analogue of a quantum geometric potential for light wave packets constrained on thin dielectric guiding layers fabricated in silica by the femtosecond laser writing technology. We further demonstrate the optical version of a topological crystal, with the observation of Bloch oscillations and Zener tunneling of a purely geometric nature. © 2010 The American Physical Society.

We show a novel technique to enhance resolution and SNR in electron microscopes-by shaping the quantum wavefunction of electrons. Our technique overcomes fundamental limits that currently set the resolution and SNR in electron microscopy. © 2015 OSA.

Electron field emission from hydrogen-terminated, H2O treated (transfer doped) diamond surfaces triggered by illumination with weak visible light (green; red; white) shows a strong dependence of the emission current on irradiation intensity, increasing by more than an order of magnitude with increasing impinging photon flux. No dependence of the emission on photon energy (color) is observed. The fact that the emission can be controlled by visible light illumination opens up the possibility to easily turn electrical currents "on" and "off", at will, at room temperature hence serving as a simple, readily available, current switch. © 2011 Elsevier B.V.

We show that it is possible to have topological transport in photonic quasicrytals, and therefore this lattices have one-way extended edgestates that are topologically protected against backscattering as they pass through defects or around corners. © 2015 OSA.
