Paper Abstract

The need for higher bandwidth in telecommunication systems is driving the development of higher power amplifiers, both EDFAs and Raman systems. This means the optical components incorporated in these amplifiers and systems must be able to withstand high power operation. In the 1400-1600-nm wavelength region, greater than 1 W of optical power is required, and in the 980-nm pump region greater than 500 mW is required. After exploring the applications for high power components, this paper discusses short and long-term failure modes that have been discovered to date. These failure modes are mainly concerned with the quality of the fiber tip and subsequent anti-reflection (AR) coatings. Component designs to eliminate these failures will be presented along with proposed tests to assure they can withstand these, and ever increasing high optical power requirements for reliable, long-term operation.
