Show affiliationsOptical amplified characteristics of inner cladding fibres with InP thin films are tested. The results indicate that this kind of fibres exhibit better optical amplification, which is advantageous for short lengths of fibres. The amplification coefficients of per unit length are 1.40–5.12 dB/m at the wave band from 906 to 1044 nm, 1.40–15.35dB/m from 1080 to 1491 nm, and 1.86–7.44dB/m from 1524 to 1596 nm. Based on the hydrogen atomic model, we calculate the comparative size of the InP particle aB = 8.313nm. The result displays the quantum size effect. By calculating the change of the energy band of particles with different sizes, the experimental data are explained by quantum size effect.
