Buried channel waveguides were fabricated in Er[sup 3+]–Yb[sup 3+] codoped phosphate glasses using focused proton beam writing. Proton ion doses in the range of 10[sup 14]–10[sup 15] ions/cm[sup 2] and 2.0 MeV energy were used. The waveguides were located 38 μm below the substrate surface and are in excellent agreement with the transport and range of ions in matter simulation. The waveguide properties were measured, and the fluorescence spectra and optical gain of the waveguides were characterized. The maximum net gain of the waveguide amplifiers at 1.534 μm wavelength was measured to be ∼1.72 dB/cm with 100 mW pump power at 975 nm wavelength. © 2004 American Institute of Physics.
