Modelling Optical Resonators Probed by Subwavelength Sized Optical Detectors
The possibility of mapping the optical field structure inside a Fabry-Perot resonator by using a pointed optical fiber was recently reported [1]. In this contribution, we propose a simulation of such near-field optical experiments by using a two-dimensional self-consistent model. The method based on the discretization of four different domains, i.e. the two mirrors, the glass sample and the tip, allows us a meaningful description of the evolution of the full field pattern when approaching the optical detector. In particular, this computerized work supply a direct illustration of the optical energy tranfer occurring when the tip enters the near-field zone. In this context, different tip desi…
Controlled Activation of Substrate Templating in Molecular Self-Assembly by Deprotonation
cited By 7; International audience; Templated assembly of organic molecules constitutes a promising approach for fabricating functional nanostructures at surfaces with molecular-scale control. Using the substrate template for steering the adsorbate growth enables creating a rich variety of molecular structures by tuning the subtle balance of intermolecular and molecule–surface interactions. On insulating surfaces, however, surface templating is largely absent due to the comparatively weak molecule–surface interactions compared to metallic substrates. Here, we demonstrate the activation of substrate templating in molecular self-assembly on a bulk insulator by controlled deprotonation of the …
