Tip-enhanced optical spectroscopy

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004
Spectroscopic methods with high spatial resolution are essential for understanding the physical and chemical properties of nanoscale materials including biological proteins, quantum structures and nanocomposite materials. In this paper, we describe microscopic techniques which rely on the enhanced electric field near a sharp, laser-irradiated metal tip.

Light with enhanced optical chirality

Optics Letters, 2012
Tang and Cohen [Phys. Rev. Lett.104, 163901 (2010)] recently demonstrated a scheme to enhance the chiral response of molecules, which relies on the use of circularly polarized light in a standing wave configuration. Here we show a new type of light that possesses orbital angular momentum and enhanced chiral response.

Optical CDMA enhanced by nonlinear optics

2010 12th International Conference on Transparent Optical Networks, 2010
Intended for the next generation of optical access networks, OCDMA is of great interest to meet the demand of increasing the number of users per access fiber, especially as spectral phase coding increases its performance in the optical domain. This, however, requires handling broad spectra and short pulses, which are best dealt with using opto ...

Extraordinary Optical Transmission Enhanced by Nanofocusing

Nano Letters, 2010
We demonstrate that the phenomenon of extraordinary optical transmission (EOT) through perforated metal films can be further boosted up by utilizing nanofocusing of radiation in tapered slits. For one-dimensional arrays of tapered slits in optically thick suspended gold films, we show that the maximum transmission at resonance is achieved for taper ...
