Welcome to the website of Oriol Arteaga. Here you will mostly hear about my research activities which mainly focus in polarimetry, ellipsometry or, more in general, in light-matter interactions. You can contact me at oarteaga(AT)ub.edu and at www.ub.edu/plat
Young’s double slit experiment is one of the most famous experiments in Physics. It played a major role in the discussion of the wave-particle duality of light and it is also usually used to explain several basic concepts of Quantum Mechanics. When the experiment is made with polarized light, the well-known result is that the…
Sorry I have not been very active updating this website lately, but research has continued and I have authored several publications since I last updated. You can see them in my Google Scholar profile and others are now under submission. Anyway, in this post I want to highlight one of my recent publications which is titled Historical revision…
I am concerned by the way the leading journal Nature deals with the subject of chirality and its relation with optics. I would say that this journal is becoming notorious for publishing papers containing confusing (and sometimes wrong) statements about chirality. Unfortunately this is not new. In 2013/2014 I sent to Nature Photonics a short…
I participate in the organization of this BIOAM Workshop that will be held in the Ecole Polytechnique (close to Paris) on 14-15 November 2016. The main subject of the workshop is Biophotonics and Optical Angular Momentum, but it will also cover many aspects about polarimetric theory, imaging. This is the complete list of topics: Fundamentals Higher…
Currently, the Ramon y Cajal program is almost the only “official” way to get into a sort of tenured-track position in Spain. The “Ramon y Cajal” 5-year contracts are funded by the Spanish Government and are addressed to professional researchers in possession of a PhD degree who have presented a line of research. Applicants must have obtained their PhD…
Last week I was in the 7th International Conference on Spectroscopic Ellipsometry celebrated this time in Berlin. This is a very nice series of conferences celebrated every 3 years (in earlier days it was every 4 years). My first participation was in Stockholm 2007 as fresh new PhD student and, later, I also participated in all the…
Relation between 2D/3D chirality and the appearance of chiroptical effects in real nanostructures, Opt. Express 24, 2242-2252 (2016) Natural optical activity vs circular Bragg reflection studied by Mueller matrix ellipsometry, Thin Solid Films Reconfigurable chiroptical nanocomposites with chirality transfer from the macro- to the nanoscale, Nature materials. Structure vs. excitonic transitions in self-assembled porphyrin nanotubes…
Cool patterns right?
When I was a PhD student I remember I often wondered why circular dichroism (CD) was measured only in transmission. At that time I was already familiar with ellipsometry measurements (in reflection) that are typically used to determine the dielectric function of materials and I did not understand why optical activity, arguably also a optical property…
“Optical activity produces a differential absorption or refraction according to the handedness of circular polarized light, but the inverse is not necessarily true: a differential absorption of refraction of circular polarized light does not imply optical activity” This simple statement has been sometimes overseen and there exist some confusion among researchers studying optical activity in several fields of…
