We report on the performance of a fiber optical parametric amplifier pumped with a temporally-incoherent pump. Parametric gain coefficients seven times higher than that of a coherently pumped amplifie...
We report less than 1-dB cross-talk penalty for 26 DWDM channels modulated at 43.7 Gb/s RZ-DPSK when amplified by a fiber optical parametric amplifier showing compatibility with high-capacity (> 1 Tb/...
We have experimentally shown that gain clamping is required in fiber optical parametric amplifiers. By using optical gain clamping (OGC), we have reduced gain variation to 1 dB, for signal input varia...
Four-wave mixing crosstalk in a fibre OPA has been reduced by 16dB by decreasing the fibre length from 340m to 50m and increasing the pump power to maintain the gain at 20dB.
We report operation of a continuous-wave one-pump fibre OPA with net gain between 1447 nm and 1717 nm. We used a 114 m long step-index highly-nonlinear fibre, and 5 W of pump power.
We used the sub-nanometer bandwidth of a bismuth-oxide fiber OPA for demultiplexing 10Gb/s channels 100GHz apart with penalty <2dB. We obtained -20dB of crosstalk, with 2.5W of CW pump power.
We obtained 6dB gain with a one-pump fiber OPA using a 3-m long Bi-HNLF fiber. Pump power was 30.2dBm.SBS suppression required 300MHz PRBS phase modulation.
RZ-DPSK OTDM demultiplexing from 40 to 10Gbps is achieved using OPA with clock-modulated pump. <1.3-dB penalty and ~28-dB gain were achieved for four demultiplexed channels.
The noise figure of a fiber optical parametric amplifier is measured at 300 and 77 K. Record low-noise, quantum- limited amplification is achieved at the Stokes frequencies.
