Engineering Fiber-Nonlinearity Based Entangled Photon Sources for Quantum Key Distribution Applications
Engineering Fiber-Nonlinearity Based Entangled Photon Sources Quantum Key Distribution Applications
2015/5/20
We model fiber parametric entangled photon sources for use in quantum key distribution applications. Effects of Raman scattered photons are evaluated and are found to be manageable when appropriately ...
Fiber Nonlinearity Mitigation by PAPR Reduction in Coherent Optical OFDM Systems via Active Constellation Extension
Fiber Nonlinearity PAPR Optical OFDM Systems Active Constellation Extension
2015/8/4
We consider Active Constellation Extension to reduce the PAPR in CO-OFDM systems. We find that the nonlinearity threshold is improved by 1.5 dB at a reach of 400 km SSMF fiber.
