Abstract We take an enhanced structure of existing optical fibres to investigate the amplification characteristics. Nano and optical fibre technologies both are employed in our structure, i.e. the so-called nano-film amplification fibre where nano-film is inserted between the core and the inner cladding of the optical fibre. In the developed model, InP is chosen as a doped semiconductor to examine its amplification performance and 69.7nm is chosen as the thickness of the film. From our experimental results, the optical fibre structure shows its significant amplification characteristics for wavelength between 1080nm and 1491nm. Amplification characteristics are also found in wavelengths 906--1044nm and 1524--1596nm.
