Abstract

A novel wideband and high‐gain waveguide‐amplifier structure, which consists of a folded geometry erbium‐ytterbium co‐doped phosphate glass waveguide integrated with a cascaded multilayer medium thin‐film filter (CMMTFF), is proposed. This CMMTFF consists of some different filter‐unit cells with different central wavelengths and bandwidths, and each of them can suppress a certain gain peak at a specific wavelength. The gain characteristics of this new optical amplifiers is obtained. © 2004 Wiley Periodicals, Inc.

## Abstract A new high‐gain Erbium‐doped fiber amplifier configured in a dual‐stage triple‐pass amplification scheme is presented. The first‐stage amplifier consists of double‐pass amplification in order to obtain high gain, while the second‐stage amplifier is single‐pass amplification. The optimum
