Going Deeper into OSNR Estimation with CNN [PDF]

Photonics, 2021
As optical performance monitoring (OPM) requires accurate and robust solutions to tackle the increasing dynamic and complicated optical network architectures, we experimentally demonstrate an end-to-end optical signal-to-noise (OSNR) estimation method based on the convolutional neural network (CNN), named OptInception.

All‐Optical Parametric‐Assisted Oversampling and Decimation for Signal Denoising Amplification

Laser &Photonics Reviews, Volume 17, Issue 6, June 2023., 2023
In digital signal processing, decimation can be employed to mitigate noise content by linearly combining consecutive samples of an oversampled signal. This article introduces an optical counterpart of digital decimation in a process referred to as Parametric‐assisted Oversampling and Decimation (POD).
