Er Glass Fiber Amplifier

The emission of Er3+ at 1530 nm has attracted special attention in telecommunication applications. Because it is in the third fiber optic communication window . This emission is critical for information transfer in Er3+ doped fiber optical amplifiers and is often used in wavelength division multiplexing networks.

Er glass fiber amplifier

Er, Yb phosphate laser glass, with its excellent fluorescence properties and chemical stability, especially the ion exchange method, can be used to make high gain per unit length, high output power, wide bandwidth, noise close to the quantum limit, independent of the polarization of the integrated optical waveguide amplifier has attracted great attention. At the same pump power, the optimal length of the phosphate-based fiber amplifier than the quartz glass-based fiber amplifier is shorter.
