Abstract :
We have demonstrated polarization-independent operation of a CW fiber optical parametric amplifier using two orthogonal pumps, with 15 dB of gain over a 20 nm bandwidth. This method is compatible with two-pump dithering to avoid idler broadening, and provides a flat-gain spectrum. Another advantage of using this method, compared with a polarization diversity scheme is that higher gain can be obtained: by using the same total pump power: we obtained 16 dB of signal gain compared to a maximum of 10 dB when using a polarisation diversity scheme. This method will help bring about the realization of practical high-quality fiber OPAs.
