Abstract
A set of phosphate glasses with different amounts of Al_(2)O_(3), Na_(2)O, La_(2)O_(3) and AlF_(3) contents were prepared to search for a phosphate glass which is suitable for ion-exchange process. Based on chemical durability test results and spectroscopic properties, a glass with excellent chemical durability and good spectroscopic properties is developed for ion-exchange process. The emission cross section of Er^(3+) in this glass is calculated to be 0.72×10^(-20) cm^(2) by McCumber theory. The planar waveguide with three modes at 632.8 nm and one mode at 1540 nm can be realized by 335 ℃ 3 hours ion-exchange in 5%AgNO_(3)+95%KNO_(3) molten salt.
