(author), Herzig, H.P. (author)We report on the experimental and numerical demonstration of immersed submicron-size hollow focused spots, generated by structuring the polarization state of an incident light beam impinging on a micro-size solid immersion lens (?-SIL) made of SiO2. Such structured focal spots are characterized by a doughnut-shaped intensity distribution, whose...journal article 2012

Assafrao, A.C. (author), Wachters, A.J.H. (author), Verheijen, M. (author), Nugrowati, A.M. (author), Pereira, S.F. (author), Urbach, H.P. (author), Armand, M.F. (author), Olivier, S. (author)Under appropriate laser exposure, a thin film of InSb exhibits a sub-wavelength thermally modified area that can be used to focus light beyond the diffraction limit. This technique, called Super-Resolution Near-Field Structure, is a potential candidate for ultrahigh density optical data storage and many other high-resolution applications. We...journal article 2012
