Tm3+-doped ion-exchanged aluminum germanate glass waveguide for S-band amplification

[摘要]：K+-Na+ ion-exchanged channel waveguide amplifiers have been fabricated in Tm3+-doped acid-resistant aluminum germanate glasses. The optical and relative gains of a 3.15-cm-long waveguide channel were achieved to be 4.05 and 2.29 dB at 1.482 mu m wavelengt
