Received Power Improvement using SOA in All-optical Networks
Network management for optical networking facing many problems as the system capacity and complexity increasing day by day that arises by using the transparent optical network components in communication system. In this article we are proposing a novel scheme of all optical networking management system. Semiconductor optical amplifier (SOA) is used after the channel to equalize the signal power...
متن کاملThe Effects of Strained Multiple Quantum Well on the Chirped DFB-SOA All Optical Flip-Flop
In this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (MQW) chirped distributed feedback semiconductor optical amplifier (DFB-SOA) all-optical flip-flop is precisely derived. We have analyzed the effects of strains of QW and MQW and cross phase modulation (XPM) on the dynamic response, and rise and fall times of the ...
متن کاملAll-optical UWB generation and modulation using SOA-XPM effect and DWDM-based multi-channel frequency discrimination.
An all-optical UWB pulses generation and modulation scheme using cross phase modulation (XPM) effect of semiconductor optical amplifier (SOA) and DWDM-based multi-channel frequency discrimination is proposed and demonstrated, which has potential application in multiuser UWB-Over-Fiber communication systems. When a Gaussian pulse light and a wavelength-tunable CW probe light are together injecte...
متن کاملSOA-based all-optical switch with subpicosecond full recovery.
We investigate all-optical switching in a multi-quantum-well semiconductor optical amplifier-based nonlinear polarization switch using optical pulses with duration of 200 fs at a central wavelength of 1520 nm. We show full recovery of the switch within 600 fs, in both the gain and absorption regime. We discuss the switching and recovery mechanisms using numerical simulations that are in qualita...
