OSNR Monitoring for NRZ-PSK Signals Using Silicon Waveguide Two-Photon Absorption
We study the use of two-photon absorption (TPA) in a silicon optical waveguide for measuring the optical signal-to-noise ratio (OSNR) of a nonreturn to zero phase-shift keying (NRZ-PSK) signal.

Considering Transmission Impairments in Wavelength Routed Networks [PDF]
— We consider dynamically reconfigurable wavelength routed networks in which lightpaths carrying IP traffic are on demand established. We face the Routing and Wavelength Assignment problem considering as constraints the physical impairments that arise in

All-optical 2R regeneration using the hysteresis in a distributed feedback laser diode [PDF]
A broadband optical 2R regenerator based on a single distributed feedback laser is demonstrated for nonreturn to zero signals at a bitrate of 10 Gb/s. A semi-analytical approach for the influence of hysteresis on the transfer function of a 2R regenerator

A Density Clustering Algorithm for Simultaneous Modulation Format Identification and OSNR Estimation
In this work, we propose a combined method to implement both modulation format identification (MFI) and optical signal-to-noise ratio (OSNR) estimation, a method based on density-based spatial clustering of applications with a noise (DBSCAN) algorithm ...

Homodyne coherent detection of ASK and PSK signals performed by a subcarrier optical phase-locked loop [PDF]
Optical transmission systems based on homodyne coherent detection of 2-ASK and pilot carrier 2-PSK signals have been implemented. ASK data has been transmitted at 2.5 Gbps, while 2.5 Gbps and 10 Gbps PSK systems have been tested.

A Joint OSNR and Nonlinear Distortions Estimation Method for Optical Fiber Transmission System
In this paper, we propose and demonstrate a joint optical signal-to-noise ratio (OSNR) and a nonlinear distortions estimation method. The OSNR is calculated by considering either the link parameters or the correlation operations of the training symbols ...
