Code for spectral amplitude coding optical CDMA systems
A new code structure for spectral amplitude coding optical code division multiple access (CDMA) is proposed and analysed. Expand
Performance study on a WDM packet switch with limited-range wavelength converters
We consider a slotted WDM packet switch with limited-range wavelength converters. Expand
Joint OSNR monitoring and modulation format identification in digital coherent receivers using deep neural networks.
We experimentally demonstrate the use of deep neural networks (DNNs) in combination with signals' amplitude histograms (AHs) for simultaneous optical signal-to-noise ratio monitoring and modulation format identification (MFI) in digital coherent receivers. Expand
Signal processing using artificial neural network for BOTDA sensor system.
We experimentally demonstrate the use of artificial neural network (ANN) to process sensing signals obtained from Brillouin optical time domain analyzer (BOTDA) and obtain temperature distribution along the fiber, especially when large frequency scanning step is adopted to significantly reduce the measurement time but without sacrifice of sensing accuracy.

This paper presents heuristic algorithms that may be used for light-path routing and wavelength assignment in optical WDM networks under dynamically varying traffic conditions. Expand
Modulation-format-independent OSNR monitoring insensitive to cascaded filtering effects by low-cost coherent receptions and RF power measurements.
We propose and experimentally demonstrate a low-cost, modulation-format-independent OSNR monitoring scheme utilizing reduced-complexity coherent receptions, electrical filtering and radio frequency (RF) power measurements. Expand
Low-complexity and phase noise tolerant carrier phase estimation for dual-polarization 16-QAM systems.
A low-complexity feed-forward carrier phase estimation (CPE) technique is presented for dual-polarization (DP)-16-QAM transmission systems. By combining QPSK partitioning, maximum likelihood (ML)… Expand
