  We demonstrate sub-picosecond wavelength conversion in the C-band via four
wave mixing in a 45cm long high index doped silica spiral waveguide. We achieve
an on/off conversion efficiency (signal to idler) of +16.5dB as well as a
parametric gain of +15dB for a peak pump power of 38W over a wavelength range
of 100nm. Furthermore, we demonstrated a minimum gain of +5dB over a wavelength
range as large as 200nm.
