Extraordinary optical transmission (EOT) is a term that refers to electromagnetic resonances through sets of subwavelength apertures in either a flat or a corrugated metal film, providing a larger transmission of electromagnetic fields than would be expected from the small aperture size. Since its discovery in 1998, EOT has been a very active research field, leading both to the discovery of new ways of enhancing optical transmission and to its application to sensing, color filters, metamaterials, lenses, optical trapping, enhancement of nonlinear effects, among others. This paper reviews the different mechanisms that lead to EOT, paying special attention to the new research areas and applications that have appeared in the last few years.

Diagnostic Tools for Lab-on-Chip Applications Based on Coherent Imaging Microscopy
Merola, F.; Memmolo, P. ; Miccio, L. ; Bianco, V. ; Paturzo, M. ; Ferraro, P.
Today, fast and accurate diagnosis through portable and cheap devices is in high demand for the general healthcare. Lab-on-chips (LoCs) have undergone a great growth in this direction, supported by optical imaging techniques more and more refined. Here we present recent progresses in developing imaging tools based on coherent imaging microscopy that can be very useful when applied into biomicrofluidics. In some cases, the optical tweezers (OT) technique is combined with digital holography (DH), thus offering the possibility to manipulate, analyze, and measure fundamental parameters of different kinds of cells. This approach can open the route for rapid and high-throughput analysis in label-free microfluidic devices and for prognostic based on cell examination, thus allowing advancements in biomedical science.
