1-Tb/s DWDM Amplification in a Fiber Optical Parametric Amplifier
Parametric oscillators amplifiers Fiber optics communications
2010/6/10
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/...
Reduced Four-Wave Mixing Crosstalk in a Short Fibre Optical Parametric Amplifier
Four-Wave Mixing Crosstalk Short Fibre Optical Parametric Amplifier
2009/7/14
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.
Continuous-Wave One-Pump Fiber Optical Parametric Amplifier with 270 nm Gain Bandwidth
Pump Fiber Optical Parametric Amplifier
2009/7/14
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.
Quantum-limited Amplification in a Fiber Optical Parametric Amplifier
Quantum-limited Amplification Fiber Optical Parametric Amplifier
2008/7/31
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.
