摘要: Buried channel waveguides were fabricated in Er3+–Yb3+ codoped phosphate glasses using focused proton beam writing. Proton ion doses the range of 1014–1015 ions/cm2 and 2.0 MeV energy used. The located 38 μm below substrate surface are excellent agreement with transport ions matter simulation. waveguide properties measured, fluorescence spectra optical gain characterized. maximum net amplifiers at 1.534 wavelength was measured to be ∼1.72 dB/cm 100 mW pump power 975 nm wavelength.
