Analysis of nonlinear effects in RSOA-based OFDM-PON

SPIE Proceedings, 2011
In this paper, a numerical investigation on the nonlinear distortion of OFDM (Orthogonal Frequency Division Multiplexed) signals caused by RSOA (Reflective Semiconductor Optical Amplifier) as an intensity modulator in OFDM-PON system is undertaken. Based on curve fitting approach a fourth order polynomial is, for the first time, used to present the ...

Improved self-seeding and carrier remodulation performance for WDM-PON by means of double RSOA erasure

, 2020
In this work, we investigated a novel wavelength division multiplexing passive optical network (WDM-PON) configuration, based on cascaded reflective semiconductor optical amplifiers (RSOA) data erasure for combined self-seeding and wavelength reuse ...

RSOA as a sawtooth generator for Rayleigh Backscattering effect mitigation

36th European Conference and Exhibition on Optical Communication, 2010
Sawtooth signal at 2.5GHz has been obtained with an RSOA of 1GHz bandwidth. A measured wavelength shifting of 2.5GHz, obtained with the RSOA chirp induced phase modulation, allows 5dB Rayleigh Backscattering effect mitigation.

Dispersion and off-set filtering in RSOA based networks

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
Next-generation access networks (NGANs) mainly include wavelength division multiplexing (WDM) based 60GHz Radio over Fibre systems (60G-RoF) and WDM Passive Optical Networks (WDM-PONs). Semiconductor optical amplifier may be the key device of colorless unit in these WDM based systems. The device can be effectively utilized as external modulator because

Modeling and simulation of RSOA with a dual‐electrode configuration

Microwave and Optical Technology Letters, 2017
AbstractBased on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower link gain when compared with a

Design Issues in RSOA-based WDM PON

2008 IEEE PhotonicsGlobal@Singapore, 2008
We review some issues critical for the design of the wavelength-division-multiplexed passive optical network (WDM PON) implemented by using reflective semiconductor optical amplifiers (RSOAs), including the uncooled operation of RSOAs, the remodulation noise, the reflectionn of SOAs,and the limited modulation bandwidth of RSOAs.

All-optical wavelength conversion in GC-RSOA

ICTC 2011, 2011
We propose a new all-optical wavelength conversion technique based on cross gain modulation (XGM) in gain clamped reflective semiconductor optical amplifier (GC-RSOA). The proposed technique uses the seed light reflected from the FBG as probe signal, thereby avoiding the need of an external seed source for wavelength conversion.

Performance of Self-Seeded RSOAs in WDM-PONs

CLEO: 2013, 2013
We present a detailed performance investigation of self-seeded RSOAs in WDM-PONs. The influences of several system parameters on the transmission performance are examined, including signal extinction ratio, stable seeding power, and features of the wavelength multiplexer.
