Security‐Enhanced Differential Binary‐Phase‐Shift‐Keying Quantum Key Distribution With a Wavelength‐Switchable Single‐Photon Carrier

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...

Interferograms of Votex FWM Beam for Nonlinear Spatial Filter in Photonic Band Gap

IEEE Photonics Journal, 2019
We analyze the properties and interferograms of vortex four-wave mixing (FWM) beams by varying the incident angle of the probe field. Based on the properties, we propose the model of a new type of nonlinear spatial filter without diffraction using a ...

Lifetime Polarization of Dressed Multiorder Fluorescence and Spontaneous Parametric Four-Wave Mixing in Pr $^{3+}$:YSO

IEEE Photonics Journal, 2015
We investigate lifetime (induced dipole-dipole interaction) of spontaneous parametric four-wave mixing (SP-FWM) and multiorder fluorescence (FL) signals controlled by polarization dressing in a heteronuclear-like molecule system of Pr3+:YSO.

Competition between FWM dynamics and modulational instability in dispersion shifted fibers [PDF]

, 2015
In this letter, we analyze the relationship between four-wave mixing (FWM) and modulational instability (MI), using numerical simulations. Our results suggest that FWM dynamics interfere on MI process, shifting its maximum frequency gain.

Comparative Performance Analysis of FWM Effect in DWDM System [PDF]

, 2016
The non linear effects degrade the system performance. Non linearity effects arose as optical fiber data rates, transmission lengths, number of wavelengths and optical power levels increased, there study become important in DWDM system.
