    "abstract": "We propose an experimental set up allowing to convert an input light of\nwavelengths about $1-2 \\mu m$ into an output light of a lower frequency. The\nbasic principle of operating relies on the nonlinear optical properties\nexhibited by a microcavity filled with glass. The light inside this material\nbehaves like a 2D interacting Bose gas susceptible to thermalise and create a\nquasi-condensate. Extension of this setup to a photonic bandgap material (fiber\ngrating) allows the light to behave like a 3D Bose gas leading, after\nthermalisation, to the formation of a Bose condensate. Theoretical estimations\nshow that a conversion of $1 \\mu m$ into $1.5 \\mu m$ is achieved with an input\npulse of about $1 ns$ with a peak power of $10^3 W$, using a fiber grating\ncontaining an integrated cavity of size about $500 \\mu m \\times 100 \\mu m^2$.",
