System feasibility of using stimulated Brillouin scattering in self coherent detection schemes

open access: yesOptics Express, 2010
We demonstrate the first self-coherent detection of 10 Gbit/s BPSK signals based on narrow-band amplification of the optical carrier by means of Stimulated Brillouin effect in a common fiber. We found that this technique is very effective only if it is combined with proper line coding and high-pass electrical filtering at the receiver.

Recent Advances in Coherent Optical Communications for Short-Reach: Phase Retrieval Methods

open access: yesPhotonics, 2023
Short-reach transmission systems traditionally utilize intensity modulation (IM) at the transmitter and direct detection (DD) at the receiver due to their cost-effectiveness, small footprint, and low power consumption.

Asymmetric self-coherent detection

open access: yesOptics Express, 2021
The bandwidth upgrade required in short-reach optical communications has prompted the need for detection schemes that combine field reconstruction with a cost-effective subsystem architecture. Here we propose an asymmetric self-coherent detection (ASCD) scheme for the field reconstruction of self-coherent (SC) complex double-sideband (DSB) signals ...

Principle and Application of the C-OTDR

open access: yesGuangtongxin yanjiu, 2022
The traditional Optical Time Domain Reflectometry (OTDR) technology uses back Rayleigh scattering power for fiber detection. In transmission lines with optical amplifier, Erbium-Doped Fiber Amplifiers (EDFA) are mostly used to compensate for the loss of ...
