Upgradable, Gain Flattened Fiber Amplifiers For Wdm Applications

View page
US Patent:
6388806, May 14, 2002
Filed:
Feb 28, 2001
Appl. No.:
09/797043
Inventors:
Paul N. Freeman - Saratoga CA
Stephen G. Grubb - Columbia MD
Daniel A. Ratoff - San Jose CA
David G. Mehuys - Sunnyvale CA
Assignee:
SDL, Inc. - San Jose CA
International Classification:
H01S 300
US Classification:
3593413, 3593411
Abstract:
A multistage optical fiber amplifier (OFA) system is designed to be upgraded with the addition of pump power when signal capacity of an optical communication link is correspondingly increased. The system includes a gain flattening filter (GFF) that remains valid when the system is upgraded because of the system design. Also disclosed are ways to enhance the GFF as well as control the channel signal gain tilt as well as adjust the external gain uniformity to be the same for an assembly line of OFA systems.

Method For Increasing Dynamic Range Of Erbium Doped Fiber Amplifiers

US Patent:
6760152, Jul 6, 2004
Filed:
Oct 11, 2002
Appl. No.:
10/269925
Inventors:
Daniel Ratoff - San Jose CA
Paul Nathan Freeman - Saratoga CA
Assignee:
JDS Uniphase Corporation - San Jose CA
International Classification:
H01S 300
US Classification:
3593413, 35934131
Abstract:
The present application relates to a doped fiber amplifier having an increased dynamic range, and particularly for laser pump sources and a method of pumping erbium doped fiber amplifiers over a greater dynamic range. In a multi-channel optical system, optical amplifiers must be able to provide gain over a larger range of signal powers, the dynamic range corresponding to the number of channels in the link. The present invention has found that the dynamic range of an EDFA can be significantly increased by using pulse width modulation to pulse pump current at or near the minimum current stability threshold, in order to produce lower power output. The duty cycle of the pulsed current is selected to achieve a time-averaged operating condition taking advantage of the relatively long relaxation time of the erbium. Thus the time averaged pump power can be reduced in a linear fashion well below the capability of a continuous wave system.
