Recent progresses in RSOA-based WDM PON

2009 11th International Conference on Transparent Optical Networks, 2009
We report on the recent progresses in the wavelength-division-multiplexed passive optical network (WDM PON) based on the reflective semiconductor amplifiers (RSOAs), including the enhanced operable temperature range, effects of reflection and its mitigation methods, 10 Gb/s operation by using electronic equalizers and forward error-correction (FEC ...

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.

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.

Analysis of reflection noise in RSOA based WDM PON

2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology, 2009
In reflective semiconductor optical amplifier (RSOA) based wavelength division multiplexing passive optical network (WDM-PON) system, reflection noise is a major factor impact on system performance. In this paper, a model experimental system is set up, in order to analyze various types of reflection noise in WDM-PON system, especially focus on the ...

Radio over RSOA-based WDM-PON

2011 International Topical Meeting on Microwave Photonics jointly held with the 2011 Asia-Pacific Microwave Photonics Conference, 2011
Reflective semiconductor optical amplifiers (RSOAs) have recently received a lot of attention as cost-effective upstream optical transmitters for wavelength-division multiplexed passive optical networks. However, the modulation bandwidth of this semiconductor device is limited to ∼1.5 GHz and the device is largely used to accommodate <2.5-Gbps ...

RSOA-based optical network units for WDM-PON

2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference, 2006
Designs of low cost ONU for WDM-PON are presented and evaluated. Reflective-SOAs are proposed to be used as core of the ONU in a bidirectional single-fiber single-wavelength topology. FEC is employed to mitigate crosstalk effects.

Wavelength-dependent characteristics of RSOA for color-free operations

Digest of the 9th International Conference on Optical Internet (COIN 2010), 2010
We investigated the wavelength-dependent operating characteristics of RSOA with external injection for color-free operation over entire wavelength range of C-band or L-band, which can be widely applicable for RSOA-based WDM-PONs.

Analysis of optical re-modulation by multistage modeling of RSOA

Optik, 2014
Abstract The time-resolved multistage reservoir model well-known for semiconductor optical amplifier (SOA) is extended to analyze the behavior of a bulk homogeneous InP-InGaAsP buried heterostructure reflective semiconductor optical amplifier (RSOA). Parameters for simulation have been extracted from the experimental RSOA characteristics.
