Wideband amplification using orthogonally polarized pulse trapping in birefringent fibers.
We analyzed the amplification effect of orthogonally polarized pulse trapping in birefringent fibers both experimentally and numerically. Trapped pulses were amplified over a wide wavelength range of 1650-1800 nm accompanying the red-shift. The maximum effective gain was 26 dB for a 140 m-long low birefringent fiber. It was clarified that this amplification effect is caused by stimulated Raman scattering between orthogonally polarized pulses.
