Quantum size effect and supercontinuum of fabricated inner cladding fibres with InP nano thin films

Based on the hydrogen atomic model, the InP, one kind of semiconductor materials Boer exciton radius have been calculated. The comparative size of the InP particle is aB=8.313nm. This article used improved chemistry vapour deposition and drawn out the fibres with InP nano thin films. By the quantum size effect, the change of the energy band of particles with different sizes and light absorption wavelength has been calculated. By using test system and nonlinear effect of fibre, supercontinuum generation can be obtained from fibres with InP nano thin films.
