MODELING OF PLANAR ION-EXCHANGED ER3-DOPED GLASS WAVE-GUIDE AMPLIFIERS()

Modeling results for Er3+-doped waveguide amplifiers fabricated by var ious ion-exchange processes are presented. The gain performance of the se devices for 0.98- and 1.48-mu m pump wavelengths are compared. Meas ured spectroscopic properties of a phosphate glass with Er3+ concentra tion of 3.7 x 10(20) Cm-3 are used throughout the modeling, and wavegu ide propagation loss of 0.1 to 0.6 dB/cm is used. It is shown that gai n coefficients exceeding 5 dB/cm are feasible utilizing optimized ion- exchanged waveguides in this glass. The modeling is performed for glas ses doped with erbium only, excluding possible ytterbium codoping. (C) 1998 Society of Photo-Optical Instrumentation Engineers.
