Postdoctoral position in experimental optics

The Langevin Institute seeks applicants to fill a 12-month Postdoctoral position in experimental optics and nano-photonics to start immediately. The candidate will work on experimental optics in disordered media in 2 directions :

- Transverse scattering and localization of light in a liquid-crystal optical valve. In this experiment he will investigate the mechanisms involved at the transition and the role of a Kerr nonlinearity in the regime of light multiple scattering.

- Active control of random laser emission. Theoretical investigations and first experiments have shown that control over the emission of a random laser can be regained by optimizing the spatial profile of the optical pump. Using an SLM-modulated picosecond pump laser, the candidate will develop an original method to control emission wavelength, directivity, pulse duration, etc ... of an optofluidic random laser.

Preferred qualifications : experimental optics and nano-photonics, laser physics, advanced simulation tools, if possible theory of random media.

Keywords : liquid crystal optical valve, random laser, active random media, nonlinear random media, nonlinear scattering, optofluidic.
