Post doc in photonic bandgap fiber / glass surface roughness characterization

The Mode-Gap European project targets the 100 fold enhancement of the overall capacity of broadband  
core networks. MODE-GAP will develop multi-mode, photonic band gap, long haul transmission, fibres 
and associated enabling technologies. These fibres offer the potential of order of magnitude capacity 
increases through the use of multiple-input multiple-output (MIMO) operation of the multi-mode fibre 
capacity and further order of magnitude capacity increases through the ultra low loss and ultra-low 
nonlinearity offered by multi-mode photonic bandgap fibre.

Within this project, we investigate the loss mechanisms due to residual surface roughness of the inner 
walls of the fibers, which are believed to be ultimately limited by the frozen capillary waves formed 
during the drawing of the fibers. To characterize and quantify these losses, high sensitivity optical 
characterization will have to be collerated to AFM measurements. For the quantitative characterization 
of such low losses, measurements will have to be pushed to their limits.

We are looking for a post doctoral researcher with a good background in instrumental optics and 
nanoscience. Prior knowledge of AFM, optical microscopy and micro-fluidics techniques will be 
appreciated. The successful candidate will develop and use measurement systems in close cooperation 
with European academic and industrial partners, in particular the Optoelectronics Research Centre (ORC)  
based at the University of Southampton.

The position is offered for a duration of 12 months.
The salary will be negociated according to CNRS salary rules.
