Strain FBG-Based Sensor for Detecting Fence Intruders Using Machine Learning and Adaptive Thresholding [PDF]

Sensors, 2023
This paper demonstrates an intruder detection system using a strain-based optical fiber Bragg grating (FBG), machine learning (ML), and adaptive thresholding to classify the intruder as no intruder, intruder, or wind at low levels of signal-to-noise ...

Simultaneous multi-channel OSNR monitoring with a wavelength selective switch

Optics Express, 2010
We show the first simultaneous OSNR monitoring of two 40 Gb/s OOK and DPSK channels, using only a wavelength selective switch and two slow photodetectors. Our approach is modulation format and bit-rate independent and can easily be included in existing reconfigurable networks.

OSNR limitations of chip-based optical frequency comb sources for WDM coherent communications [PDF]

arXiv, 2019
Optical frequency combs have the potential to become key building blocks of optical communication subsystems. The strictly equidistant, narrow-band spectral lines of a frequency comb can serve both as carriers for massively parallel data transmission and as local oscillator for coherent reception.

Transfer learning assisted deep neural network for OSNR estimation

Optics Express, 2019
We propose a transfer learning assisted deep neural network (DNN) method for optical-signal-to-noise ratio (OSNR) monitoring and realize fast remodel to response to various system parameters changing, e.g. optical launch power, residual chromatic dispersion (CD) and bit rate. By transferring the hyper-parameters of DNN at the initial stage, we can fast

Optimisation algorithms for OSNR measurement based on polarisation nulling [PDF]

Electronics Letters, 2015
Optimisation algorithms are demonstrated as a nulling finder for an in‐band optical signal‐to‐noise ratio (OSNR) monitoring method based on polarisation extinction. The method was tested and validated in the Brazilian GIGA optical fibre testbed. When three optimisation techniques (genetic algorithm, particle swarm optimisation (PSO) and downhill ...

Simulations of an OSNR-Limited All-Optical Wavelength Conversion Scheme [PDF]

IEEE Photonics Technology Letters, 2013
We present simulations of a scheme to perform wavelength conversion of signals that eliminates phase-noise transfer from the pump to the converted signal. Nondegenerate four-wave mixing in a semiconductor optical amplifier is used to convert the signal to a new wavelength, and if an optical comb generator is used as the multiple-pump source, then the ...

An Ultracompact OSNR Monitor Based on an Integrated Silicon Microdisk Resonator

IEEE Photonics Journal, 2012
Optical signal-to-noise ratio (OSNR) monitoring is essential for control and management of dynamic optical networks. Small footprint, low cost, and less power consumption are always desirable for such monitoring system.
