Vertical cavity lasers (VCSEL)

Contact: G. Almuneau, V. Bardinal, C. Fontaine
Vertical-cavity surface-emitting lasers (VCSELs) have gained great attention as an attractive light source for short-distance optical communication systems, optical interconnects optical storage, and laser printing. The proven potentials and flexibility of these optoelectronic devices have recently attracted much attention from other fields of application such as microsensors and biomedical instrumentation.
Due to this new interest, derivate functionalities have now to be developed to further extend the integration capabilities of the VCSELs in microsystems.
Two aspects have to be addressed in this prospect: the adaptation of the laser source to the microsystem, and the diversification and/or association of other optical functionalities.
