Reflective Semiconductor Optical Amplifier Chip with Low Ripple for C-Band External Cavity Narrow-Linewidth Laser

open access: goldPhotonics
The main characteristic of a reflective semiconductor optical amplifier chip (RSOA) is that it does not generate optical resonance under electric pumping and maintains the operation state of spontaneous emission.

Time Delay and Gain Reduction in Reflective Semiconductor Optical Amplifier

open access: green2018 11th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2018
Amplification of picosecond optical pulses by reflective semiconductor optical amplifier (RSOA) is theoretically investigated using a high-precision time-domain model. It is demonstrated that, compared to conventional SOA in similar conditions, pulses amplified by RSOA suffer from additional gain reduction of a few dB due to RSOA’s rear-facet ...

Modeling reflective bistability in vertical-cavity semiconductor optical amplifiers [PDF]

open access: greenIEEE Journal of Quantum Electronics, 2005
The characteristics of optical bistability in a vertical cavity semiconductor optical amplifier (VCSOA) operated in reflection are reported. The dependences of the optical bistability in VCSOAs on the initial phase detuning and on the applied bias current are analyzed.

Analytic Study of the Modulation Response of Reflective Semiconductor Optical Amplifiers [PDF]

open access: bronzeJournal of Lightwave Technology, 2015
We study the modulation response of a reflective semiconductor optical amplifier (RSOA) operated by directly modulating its injection current. We derive an analytic expression for the 3 dB modulation bandwidth, and characterize its dependence on the main RSOA parameters. Our study is based on a reduced model for the nonlinear RSOA response.

All-optical Regenerator Using Semi-reflective Semiconductor Optical Amplifier [PDF]

open access: bronzeJournal of the Optical Society of Korea, 2006
We have proposed and theoretically verified an optical regenerator using a single semi-reflective semiconductor optical amplifier (SR-SOA). To explain the operation characteristics and the operation condition of the proposed opticalregenerator, the simplified gain model for the SR-SOA is introduced and confirmed by comparing the result of the SOA ...

All-optical power equalization based on a two-section reflective semiconductor optical amplifier

open access: goldOptics Express, 2013
A simple all-optical power equalization scheme based on a single two-section reflective semiconductor optical amplifier (RSOA) is presented. Double optical path and non-uniform injection current density in the two sections easily saturate the RSOA and suppress pattern effect, thereby significantly reducing packet-to-packet power fluctuation while ...
