The Co-doped TiO,2 films (Co,0.1 Ti,0.9 O,2-δ) are prepared on silicon substrates by sol-gel method and post annealing. The Co,0.1 Ti,0.9 O,2-δ film annealed
Using numerical calculation, we examine the effects of gap distance of a pair of nano gap silver prisms with rounded coers on the local light intensity enhancem
We demonstrate a pulse compression technique through filamentation in an argon-filled cell By using a pair of chirped mirrors for dispersion compensation, we ha
Fibre Bragg gratings (FBGs) are inscribed in homemade microstructured fibres by the standard phase mask method. Enhanced couplings between the forward fundament
