Coexistence of continuous variable QKD with intense DWDM classical channels
, 2015 We demonstrate experimentally the feasibility of continuous variable quantum key distribution (CV-QKD) in dense-wavelength-division multiplexing networks (DWDM), where QKD will typically have to coexist with several co- propagating (forward or backward ...

Performance Analysis of DP‐QAM‐Based Optical OFDM PON Employing Optical Multicarrier
Journal of Engineering, Volume 2024, Issue 1, 2024.This work proposes a new hybrid bidirectional standard single mode fiber (SSMF)/free space optical (FSO) dual polarization quadrature amplitude modulation (DP‐QAM) employing optical orthogonal frequency division multiplexing (OFDM). An optical multicarrier generator (OMG) source is utilized. The suggested model is simulated using VPI photonics software.
