Abstract

A unique method of upgrading a C‐band EDFA into a highly efficient L‐band EDFA is presented, incorporating a gain‐clamped amplifier (ring laser) that acts as a gain‐improving element in an unpumped erbium‐doped fiber. A gain improvement of 17.8 dB and noise figures <4.0 dB are measured for optimum settings. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 282–284, 2001.
