“…We now compare the evolution of the gain curves with pump power for different schemes. For PSA based on secondharmonic generation in [35,36] and with low average pump power, the maximum and minimum gain are symmetrical. The gain is inherently asymmetrical at a high-power level based on the theory in [37], specifically the deamplification is much larger than the amplification.…”

We experimentally demonstrate phase-sensitive amplification based on pump-degenerate four-wave mixing in dispersion-engineered chalcogenide waveguides. We achieve a maximum extinction ratio of 18 dB with a pump peak power of 6.7 W. The variation of the gain as a function of relative phase, pump power, and bandwidth is theoretically analyzed and experimentally studied. Additionally, an analytical formula relating the phase-transfer curve to the experimental gain curve is derived. Numerical calculations show strong agreement with the experimental results.

“…Phase sensitive processing had until now only been demonstrated under practical CW pumping configuration in HNLFs [5] and χ (2) materials [6], as well as in chalcogenide waveguides [7] and Si photonic crystal (PhC) waveguides, but only under pulsed operation [8].…”

“…Alternative nonlinear materials may offer more compact implementations as well as better SBS immunity. Phase-sensitive amplification has been successfully shown by exploiting second order nonlinearities in periodically-poled lithium niobate (PPLN) waveguides [3][4][5]. Recently, the first demonstration of phase-sensitive amplification exploiting third order nonlinearities in a waveguide has been reported using chalcogenide glass [6].…”

Phase regeneration of differential phase-shift keying (DPSK) signals is demonstrated using a silicon waveguide as nonlinear medium for the first time. A p-i-n junction across the waveguide enables decreasing the nonlinear losses introduced by free-carrier absorption (FCA), thus allowing phase-sensitive extinction ratios as high as 20 dB to be reached under continuous-wave (CW) pumping operation. Furthermore the regeneration properties are investigated under dynamic operation for a 10-Gb/s DPSK signal degraded by phase noise, showing receiver sensitivity improvements above 14 dB. Different phase noise frequencies and amplitudes are examined, resulting in an improvement of the performance of the regenerated signal in all the considered cases.
