|Abstract:||The capacity of communication networks may be significantly improved by simply enhancing the optical amplifier bandwidth. This paper presents a numerical investigation of an ultra-broadband, low-ripple, two-pump-optical parametric amplifier (2P-OPA) that employs a tellurite glass buried-channel type nano-waveguide as nonlinear medium. The nano-waveguide was designed as a 25-cm-long Archimedean spiral that occupies a footprint of only similar to 2.5 mm(2), with a similar to 0.7 mu m(2) effective cross section. Its zero-dispersion wavelength is similar to 1550 nm, the nonlinear coefficient is similar to 3000 W-1 km(-1), and the attenuation coefficient is similar to 0.5 dB/m (1100 to 1900 nm). Simulations suggest a 2P-OPA based on such waveguide will be able to amplify 243 QPSK input channels modulated at 56 Gbps over 102 nm bandwidth, over metropolitan area network scales.
