1 FOREWORD

Increasing demands for the high-capacity wavelength division multiplexed (WDM) transmission system now require the development of new transmission windows exceeding the gain bandwidth formerly supported by Erbium-doped fiber amplifiers (EDFA). With intensive development efforts on new rare-earth dopants, high power laser diodes, and highly-nonlinear fiber in the past years, today’s wideband optical amplifiers now can easily support gain ...
