Design and Simulation of Erbium Doped Waveguide Amplifiers

摘要

The erbium doped waveguide amplifier (EDWA) provides the benefits of high gain per unit length and compact size. We use the erbium two-level system model with the measured material properties and waveguide properties to study the amplifier performance dependence on operating conditions and EDWA lengths. We have established a modeling, simulation, and design framework to systematically study the amplifier performance issues from materials to device packaging. Simulations of two EDWA examples based on alumino-silicate and phosphate glasses are carried out in detail.
