Modeling and simulation of dynamics and noise of semiconductor lasers under NTSC modulation for use in the CATV technology by Alaa Mahmoud, Safwat W.Z. Mahmoud, Kamal Abdelhady

“…When the modulation index exceeds 43%, i.e. the modulation current exceeds the bias level above threshold, the laser emits clipped signals superposed by relaxation oscillation. The increase in the modulation index by about 50% in channels beyond channel #24 makes the laser emitting clipped pulsed signals superposed by relaxation oscillation. …”

Coupled-Cavity VCSEL with an Integrated Electro-Absorption Modulator: Small- and Large-Signal Modulation Analysis by Krassimir Panajotov, Richard Schatz

“…For current modulation, the cut-off frequency remains limited by relaxation oscillation frequency. For EAM loss modulation, the MTF curve is much flatter and its shape around the relaxation oscillation frequency displays either a well-pronounced maximum, both a maximum and a minimum or a sharp minimum only depending on the bias point of the EAM losses. …”

CW Emission and Self-Pulsing in a III-V/SiN Hybrid Laser With Narrow Band Mirror by Cristina Rimoldi, Lorenzo L. Columbo, Jock Bovington, Sebastian Romero-Garcia, Mariangela Gioannini

“…We report on how external cavity III-V/SiN hybrid lasers operate in regimes of ultra-damped relaxation oscillations or in CW unstable dynamical regimes (self-pulsing or approaching turbulence) as a consequence of mirror dispersion, non-zero linewidth enhancement factor, and four-wave mixing in the gain medium. …”

Enhanced gain saturation model of non-linear semiconductor optical amplifiers by Kharraz, Osayd M., M. Supa'at, Abu Sahmah, Atieh, Ahmed, Abdul Kadir @ Jaafar, Muhammad Zamzuri, Mahdi, Mohd Adzir

“…The rate equations are utilised with the extra gain compression term for Indium-Gallium-Arsenide material-based SOA to account for the steep relaxation oscillations behaviour of non-linear SOAs. The proposed gain saturation model is verified with experimental results that showed very good agreements with a mean square error of 0.094.…”

General Properties of Near-Contact Binaries by Kyu-Dong Oh, Ho-Il Kim, Young Woon Kang, Woo-Baik Lee

“…The evolutionary status of the F type near-contact binaries are closer to that of the contact systems, i.e., W UMa type binaries, if it is assumed that the evolution of the NCBs is governed by the thermal relaxation oscillation theory. The mass-radius relation, mass-luminosity relation and H-R diagram of the NCBs provide that the A type NCBs suffer from more active mass transfer than F types. …”
