Eight-Wavelength Er-Yb Doped Amplifier : Combiner/Splitter Planar Integrated Module

Abstract - We report the successful operation of a pigtailed eight-wevelength planar integrated amplifying combiner. This device can be used in a splitter or in a combiner configuration. It consists in an 8 x 1 combiner and a 5.5-cm Er-Yb-doped waveguide amplifier. The module provides net gain simultaneously to the eight combined wavelengths in the 1531-1546-nm optical bandwidth. This module has been incorporated in an 8 x 2.5 Gb/s wavelength-division-multiplexed (WDM) system. The central wavelength was 1535 nm and the channel spacing was 1 nm. Negative penalty for bit-error-rate performances (BER<10-10) has been measured for each wavelength. The results of the system performance demonstrate the potential of the ion-exchange technology in providing cost effective integrated optic solutions for WDM networks applications.
