Phase Sensitive Degenerate Parametric Amplification Using Highly Efficient PPLN Ridge Waveguides
Nonlinear optics parametric processes Lithium niobate
2011/5/22
We constructed the first CW pumped degenerate parametric amplifier based on PPLN waveguides. We successfully demonstrated an in-phase gain of +11 dB and the phase sensitive amplification of a modulate...
C+L Band Remote Node for Amplification in Extended Reach Full-Duplex 10Gb/s WDM/TDM Passive Optical Networks
C+L Band Remote Node Extended Reach Full-Duplex WDM/TDM Passive Optical Networks
2009/7/20
A remote node design for C+L band amplification is shown to cover the advanced optical power budget for a 50km reach, symmetrical 10G/10G WDM/TDM-PON. 5-10dB of margin is left despite OSNR degradation...
Multi-wavelength amplification and signal processing in InP based quantum dash semiconductor optical amplifiers
Multi-wavelength amplification signal processing semiconductor optical amplifiers
2009/7/16
We describe multi-wavelength amplification and processing of quantum dash amplifiers. The multi-wavelength operation is possible due to the inhomogeneously broadened gain.
Impact of Pump-Induced Nonlinear Phase Noise on Parametric Amplification and Wavelength Conversion of Phase-Modulated Signals
Pump-Induced Nonlinear Phase Noise Parametric Amplification Wavelength Conversion Phase-Modulated Signals
2009/7/15
We calculate the signal SNR penalty resulting from pump-induced nonlinear phase noise in dual-pump fibre optical parametric amplifiers for various phase-shift keying formats.
