Abstract

The proton beam writing (PBW) used to fabricate buried channel waveguides in Er³⁺-Yb³⁺ codoped with phosphate glass was investigated. Single 2.0 MeV proton beam energy and proton ion doses in the range of 10¹⁴-10¹⁵ ions/cm² were used. The fluorescence and amplified spontaneous emission (ASE) spectra of the bulk glasses and waveguides were also measured. The results show that the net gain of the waveguide amplifiers at 1.534 μm single wavelength was ≅ 1.72dB/cm at 975 nm wavelength with 100 mW pump power.
