Abstract
⺠Active waveguides in GeO2-PbO-Ga2O3 glass doped with Er3+ by direct fs laser writing. ⺠Permanent refractive index change was obtained and estimated to be â¼6 Ã 10â3. ⺠The minimum propagation loss at 1532 nm was 4.8 dB/cm. ⺠Waveguides were formed under different laser pulse energies and scan velocities. ⺠Maximal internal gain of 2.7 dB/cm at 1.5 μm under 980 nm excitation was achieved.
