Cavity solitons (CS) are solitary waves in a nonlinear optical cavity (see 'Overview').
The FunFACS project aims at greatly enhancing the scope of cavity soliton science and technology through research into their Fundamentals, Functionalities, and potential Applications. It proposes to realise scientific breakthroughs with a large potential impact in opto-electronics by the demonstration of self-sustained cavity soliton lasers based on semiconductor lasers, i.e. devices where all energy is drawn from an incoherent source.
In particular, it is aimed at
- realizing a cavity soliton laser in the continuous wave regime where the light field is spatially localized in the two dimensions transverse to the cavity axis.
- realizing a cavity soliton laser in a pulsed regime. The final vision is a localisation of light in all three "transverse plus longitudinal" dimensions and thus the realization of cavity light bullets.
- realizing experimental proofs of principles for embryonic all-optical processing functionalities specific to CS properties. These demonstrators will use and possibly combine driven and self-sustained laser devices.
Finally, the project is concerned with the fun of working with cavity solitons.
The project terminated with a successful review on Nov 28, 2009.
