Comparative analysis of the dispersion compensating fiber (DCF) scheme in long-haul dense wavelength division multiplexing (DWDM)

Journal of Physics: Conference Series, 2019
Abstract Dense wavelength division multiplexing (DWDM) technique in optical communication was used to improve the system performance combined several channels in a transmission line especially for long-haul optical link, but the presence of dispersion limited the system performance.

Non‐Markovian Dynamics in Fiber Delay‐Line Buffers

Advanced Quantum Technologies, Volume 8, Issue 8, August 2025.
A qubit‐fiber birefringence‐reservoir model is proposed to explore the non‐Markovian dynamics of the fiber‐based buffered photon and its paired photon. The non‐Markovian probability function is obtained by performing full quantum state tomography. The probability function fits well with experimental data and physical values.

Experimental Demonstration of π Equivalent Phase-Shifted SBG Laser With Controlled Distributed Phase Shift

IEEE Photonics Journal, 2019
We designed and fabricated a π equivalent phase-shifted sampled Bragg grating (SBG) semiconductor laser with a controlled distributed phase shift. The phase shift is equivalently realized with reconstruction-equivalent-chirp (REC) technique.

Electrically tunable ring resonators incorporating nematic liquid crystals as cladding layers [PDF]

, 2003
We have demonstrated electrical tuning in ring resonators fabricated from silicon-on-insulator wafers by incorporating nematic liquid crystals (NLCs) as the waveguide top and side cladding material. Photolithographically defined electrodes aligned around

On‐chip frequency‐bin quantum photonics

Nanophotonics, Volume 14, Issue 11, Page 1879-1894, June 2025.
Abstract Frequency‐bin encoding furnishes a compelling pathway for quantum information processing systems compatible with established lightwave infrastructures based on fiber‐optic transmission and wavelength‐division multiplexing. Yet although significant progress has been realized in proof‐of‐principle tabletop demonstrations, ranging from arbitrary ...
