Optimization of the properties of dichroic PC-VCSELs with vectorial and semi-vectorial methods

 

The results obtained during the STSM will be presented on the ICTON conference in Athens, Greece, 22-26 June 2008.

Furthermore, a publication on the subject is currently in preparation. In the article we will show in details our numerical results and discuss the applicability of photonic-crystals for polarisation control in VCSELS.

In summary the reported STSM was very useful and resourceful for the work of modelling PC-based VCSELs done in cooperation between Technical University of Lodz and Vrije Universiteit Brussel.

Solitonic Coherent Collisions in Photorefractive Iron Doped Indium Phosphide

 

The reported work is only a  first stage and future collaborations have been planned in order to complete the characterization of the interaction processes and moreover to develop a working model for photorefractivity.

The obtained results are quite promising as we chose a condition for which the efect are expected to be minimized, because of the minimization of the photorefractive gain.

We think that it is possible to strongly improve the repulsion e_ect so to get a Real all-optical routing device.

Theoretical & experimental knowledge exchange in the photonic devices area

 

Future collaboration with host institution: The possibility of having a visit from the host visiting one or both of the two visiting institutions was discussed in order to increase the know-how exchange and the scientific results validation by means of simulation activity.

Projected publications/articles resulting or to result from the STSM: A preliminary report activity will be prepared during the MC/WG meeting at ICTON 2009. One or two articles on the subject are predicted in the next months, especially on the simulation validation of the organic/inorganic device structure for low cost TLC applications.

HNLF and PCF application for fast all optical signal elaboration

We intend to continuing the study the system, we are especially interested in using high er pumps level, especially the L band pump, to see the effect of a higher and flatter gain.

Moreover we will try to use some PCF to see the possible reduction of the non linear spam of fiber.

Another use of this technique can be the time domain demultiplexing archievable modulating one or both the pumps in order to select in the replica only one of the tributary channel.

Nonlinear refractive index of quantum dot samples

 

This measurement taken and analyzed successfully has opened a new channel for future collaboration between the University of Strathclyde and CNRS.

We are planning to extent the collaboration with a visit in autumn with a probable

financial support applied at CNRS. It is expected that the results obtained then with the improvements mentioned will lead to results publishable in a refereed journal.

The Strathclyde side is planning to set up a complementary experiment on their 1300 nm QD samples, probably using first interference with an external reference beam. Sensitivity and other pros and cons of these two interferometric approaches will be compared.

A proposal for a 2-year international collaboration grant will be submitted to the Rogal Society / CNRS in June.

Light propagation in nonlinear slow-light polymeric photonic structures

The outcome of the STSM was the identification on a new and fruitful research direction which will be pursued by both groups. During the STSM a preliminary analysis of the nonlinear coupled microrings structure was carried out and a self-consistent procedure was developed to tune the structure in order to achieve a resonant condition ("dark-state") for any given wavelength. In addition, a nonlinear time-domain formalism was developed in order to examine the stability properties of the self-consistent solution.

The next step is to implement the time-domain formalism numerically and study the dynamics of the nonlinear system. In particullar, the formalism will be used to study the stability properties of the solution, its sensitivity to perturbation and additional dynamical properties such as stabilization time constants, switching time, etc.

Second harmonic generation in materials with nonlinear random distribution

The results achieved in the framework of my collaboration with the group of Wieslaw Krolikowski and Yuri Kivshar, one of the leading laboratories in the field of the nonlinear optics, were very satisfactory and very interesting. I think that in this short tine we have considerably advanced both in our experimental and theoretical investigation. We will continue to collaborate in the future on several topics related to the nonlinear interactions in random materials.

My visit to CUDOS ANU, thanks to the STSM in the framework of COST MP0702 was very fruitful and I consider it crucial for our future collaboration
