Optimization of Raman amplifiers: a comparison between black-, grey- and white-box modeling

no code implementations11 Sep 2023 Metodi P. Yankov, Mehran Soltani, Andrea Carena, Darko Zibar, Francesco Da Ros

Designing and optimizing optical amplifiers to maximize system performance is becoming increasingly important as optical communication systems strive to increase throughput.

Experimental validation of machine-learning based spectral-spatial power evolution shaping using Raman amplifiers

no code implementations26 Sep 2022 Mehran Soltani, Francesco Da Ros, Andrea Carena, Darko Zibar

In this case, the experimental results assert that for 2D profiles with the target flat gain levels, the DE obtains less than 1 dB maximum gain deviation, when the setup is not physically limited in the pump power values.

Experimental Validation of Spectral-Spatial Power Evolution Design Using Raman Amplifiers

no code implementations16 May 2022 Mehran Soltani, Francesco Da Ros, Andrea Carena, Darko Zibar

We experimentally validate a machine learning-enabled Raman amplification framework, capable of jointly shaping the signal power evolution in two domains: frequency and fiber distance.

Deep Feature Selection using a Teacher-Student Network

1 code implementation17 Mar 2019 Ali Mirzaei, Vahid Pourahmadi, Mehran Soltani, Hamid Sheikhzadeh

In this paper, we present a novel teacher-student feature selection (TSFS) method in which a 'teacher' (a deep neural network or a complicated dimension reduction method) is first employed to learn the best representation of data in low dimension.

Deep Learning-Based Channel Estimation

4 code implementations13 Oct 2018 Mehran Soltani, Vahid Pourahmadi, Ali Mirzaei, Hamid Sheikhzadeh

This scheme considers the pilot values, altogether, as a low-resolution image and uses an SR network cascaded with a denoising IR network to estimate the channel.
