04 December 2007 ICFO congratulates a new PhD graduate

Dr. Maymó during his thesis dissertation


Thesis Committee

Dr. Marc Maymó obtained his Doctoral Degree with a project on nonlinear photonic crystals supervised by Prof. Jordi Martorell. Dr. Marc Maymó got an Industrial Engineering degree from the Universitat Politècnica de Catalunya in 2000. Since 2001 he has been working in the field of nonlinear photonic crystals in Martorell’s group at the UPC and at ICFO.

Marc Maymó research project studies the possibility to reach second order nonlinear interactions within materials with a center of inversion symmetry.

Second order nonlinear interactions are, among, the most relevant nonlinear interactions between light and matter when one considers their applications. Such interactions are only efficient in noncentrosymmetric materials and materials or material structures that provide a phase matching mechanism. This is the case, for instance, in highly anisotropic crystals. However such anisotropy sets important limitations to the application scope of these materials. Photonic crystals have the capability of controlling the propagation and generation of light. The high number of interfaces present in the photonic crystal structure, where a quadratic nonlinear interaction may occur, and the band edge effects, make it interesting to focus our study into some of such second order nonlinear interaction. The main objective of Marc’s dissertation has been the experimental and theoretical results related to different second order nonlinear interactions in the framework of nonlinear colloidal photonic crystals, and nonlinear opals.
