All-Optical 2R Regeneration of BPSK and QPSK Data using a 90° Optical Hybrid and Integrated SOA-MZI Wavelength Converter Pairs
Coherent communications Wavelength conversion devices
2015/5/20
We demonstrate all-optical 2R regeneration with a 90° optical hybrid and integrated MZI-SOA pairs for 10 Gb/s BPSK and 20 Gb/s QPSK with negative power penalty. Power penalty and OSNR improvements of ...
Polarization Independent Dual Wavelength Converter Based on FWM in a Single Semiconductor Optical Amplifier
Wavelength conversion devices SOA Nonlinear optics FWM
2015/6/10
We present a FWM-based dual channel wavelength converter in an SOA with very small variations in conversion efficiency and a minor polarization related power penalty of 0.9dB between best and worst ca...
Balancing Multifibre and Wavelength Converter Cost in Wavelength Routing Networks
Balancing Multifibre Wavelength Converter Cost Wavelength Networks
2015/8/6
This paper evaluates the balance between the cost of multifibres and the cost of wavelength converters in multilayer networks. A novel ILP formulation of the static planning problem is applied.
All-optical Vestigial-Sideband Signal Generation and Pattern Effect Miti- gation with an SOA Based Red-Shift Optical Filter Wavelength Converter
All-optical Vestigial-Sideband Signal SOA Based Red-Shift Optical Wavelength Converter
2015/8/3
We demonstrate 40 Gb/s SOA-based wavelength conversion from a RZ into a vestigial-sideband RZ signal. SOA related pattern effects are successfully suppressed by proper choice of the red-shift optical ...
