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.

Rayleigh noise suppression with cascaded RSOAs in WDM-PON system

2013 22nd Wireless and Optical Communication Conference, 2013
In single fiber bidirectional central light seeding wavelength division multiplexing passive optical network (CLS WDM-PON), Rayleigh backscattering (RB) noise is the main factor limiting system performance. We propose and demonstrate a cascaded reflective semiconductor optical amplifiers (RSOAs) structure to suppress signal RB noise in WDM-PON ...

RoF using optically equalized RSOA WDM-PON architecture

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
In this paper Reflective Semiconductor Optical Amplifier (RSOA) based Wavelength Division Multiplexing-Passive Optical Network (WDM-PON) architecture is enhanced to carry radio frequency (RF) signals using an optical offset filtering technique in order to overcome the RF bandwidth limitation of the architecture.

Build-up analysis of an RSOA-based self-seeded transmitter

2014 The European Conference on Optical Communication (ECOC), 2014
A different approach, focusing both on the power build-up and the optical spectrum build-up of the RSOA-based self-seeded transmitter, uncovers that steady-state is reached later than expected. Initial roundtrips are analysed to enlighten the mechanism of radiation formation from ASE.

Demonstration of WDM-PON using spectrum-sliced RSOA

SPIE Proceedings, 2006
We present a low-cost WDM-PON employing colorless uncooled RSOA-based spectrum sliced sources. Colorless operations over 32 WDM channels are demonstrated from 0 to 60 o C in 155-Mb/s transmissions over 25 km.

A Review of Self-Seeded RSOA Based on WDM PON

Canadian Journal of Electrical and Computer Engineering, 2019
The colorless technology has been offered as a solution to decrease the cost in wavelength-division multiplexed passive optical network (WDM PON). The self-seeded reflective semiconductor optical amplifier (SS-RSOA) based on WDM PON has been proved to be a promising solution among colorless operations.
