Effects of concentration and clusters in EDFAs

Optical Fiber Communications Conference, 1995
Strong interest in heavily doped erbium-doped waveguides1 and in the applications of heavily doped erbium-doped fibers (EDFs) in lasers has resulted in several recent studies of collective processes in erbium ions. Rapid cross relaxation within a fraction of clustered ions, called pair-induced quenching (PIQ), has been identified as the main cause of ...

The signal and pumping power for EDFA

2003 International Semiconductor Conference. CAS 2003 Proceedings (IEEE Cat. No.03TH8676), 2004
In this work, we determine the optical signal power and the pumping power for EDFA as function of the distance along the optical fiber. The method used for the computing of the numerical solutions for optical signal power and pumping power is the Runge-Kutta method with fourth-order accuracy.

Communications performance of a multimode EDFA

IEEE Photonics Technology Letters, 2000
We report an investigation of a multimode EDFA used as an optically preamplified receiver. A two-stage amplifier pumped at 982 nm shows gain of up to 40 dB at 1553 nm. We study the communications performance of the receiver at 10 Gb/s and compare it with theory.

The EDFA: past, present and future

Fifth Asia-Pacific Conference on ... and Fourth Optoelectronics and Communications Conference on Communications,, 1999
Summary form only given, as follows. More than thirteen years have elapsed since the first experimental demonstration of a high-gain erbium doped fibre amplifier. Since then the aggregate bandwidth of optical fibres has increased dramatically with the deployment of WDM systems.

Hybrid EDFA/Raman Amplifiers

2004
This chapter describes the technologies needed for cascading an erbium-doped fiber amplifier (EDFA) and a fiber Raman amplifier (FRA or RA) to create a hybrid amplifier (HA), the EDFA/Raman HA. Two kinds of HA are defined in this chapter: the narrowband HA (NB-HA) and the seamless and wideband HA (SWB-HA).
