Organic photonics and nanostructures (PON)

The Photonics axis concentrates on organic photonics devices and studies the underlying physics of these components. The axis is composed of three teams:

Team 1: Lasers and organic photonics team – study of organic lasers under optical excitation with applied and fundamental perspectives (voir le site Web) ;

Team 2: Photonics and Nanostructures team comprised of two sub-teams:

2.1 : Organic laser under electrical pumping : focus on molecular plasmonics and OLEDs in micro cavity ;

2.2 : Non-linear photonic crystals ;

Team 3: Light-materials interactions team: non-conventional laser techniques for surface structuring, study of the physical and chemical mechanisms photo-induced on inorganic and hybrid materials.

The current activities of the group focus on two main axes: organic lasers and non-linear photonic crystals.

 

Organic lasers

The main objective of the first axis is the realization of an electrically pumped organic laser diode. In this context, the team is interested in three aspects: optimization of the laser cavity, improvement of optical and electrical performances of organic light-emitting diodes (OLED) using plasmonic effect and electrical pulsed excitation. Specifically, the team is interested in the parameters and conditions that make it possible to transform an OLED into an Organic Laser Diode (DLO) similar to what happened when transforming an LED into a laser diode of inorganic semiconductor materials.

Non-linear photonic crystals

The objective of the second axis concerns the use of the flexibility offered by the PPLN and 2D PPLT structures in order to produce multi-wavelength and / or broadband laser sources. In this context, the team is working on the study of optical parametric oscillation and generation in nonlinear two-dimensional photonic crystals. More recently, the team is also interested in the realization and study of 3D PPLN and PPLT structures using an original technique under development. It should be noted that this research is carried out in the framework of an international collaboration with the National Taiwan University of Taipei (Taiwan).
