All-Optical Non-Inverted Parity Generator and Checker Based on Semiconductor Optical Amplifiers
An all-optical non-inverted parity generator and checker based on semiconductor optical amplifiers (SOAs) are proposed with four-wave mixing (FWM) and cross-gain modulation (XGM) non-linear effects. A 2-bit parity generator and checker using by exclusive

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.

Proactive and Nondisruptive Channel Probing for Wavelength Switching in Optical Transmission
Proactive and nondisruptive channel probing is investigated for the measurement of channel power, amplifier channel gain, and optical signal-to-noise ratio (OSNR) without disrupting established wavelength-division multiplexed channels.

ASE Noise in Raman Amplifiers: Pump Depletion Impact [PDF]
This paper provides a detailed analysis for the effect of pump depletion on amplified spontaneous emission (ASE) noise power, optical signal to noise ratio (OSNR), and noise figure (NF) in forward pumped distributed Raman fiber amplifier (DRFA).
