  • Abstract
    Preliminary observations and measurements of increased relaxation speeds for optical switching in resonantly enhanced nonlinear systems are demonstrated. The effect is observed using a neodymium-doped twin-core fibre interferometer, and uses stimulated down-pumping of the 4F3/2 metastable state in neodymium. The relaxation time has been reduced from ~390 μs to less than 120 μs, and it is shown that the reduction is dependent on the power of the down-pumping source
