Dielectric multilayer structures fabricated by rf-sputtering

Optically confined structure is a fundamental topic in both basic and applied physics including potential application in information engineering, biological and medical sciences, sensing. In this scenario one-dimensional photonic crystals have been widely investigated and still remain an outstanding tool for new photonics, being the simplest system to exhibit a so-called photonic bandgap and therefore one of the easiest to handle in order to obtain tailored optical devices. RF sputtering techniques has demonstrated to be a viable technique for fabrication of 1D-photonic crystals allowing management and manipulation of the spectroscopic properties of optical and spectroscopic properties
