摘要：

We have developed mode-tunable waveguides through femtosecond laser direct writing in glass. The structural changes and formation mechanisms were investigated by Raman mapping. The waveguide exhibited a record- low propagation loss of 0.14 dB/cm and an insertion loss of 0.23 dB at 520 nm. This work presents a new technique for producing waveguides for visible light photonic integrated devices.
