Abstract

We report a dual-wavelength (DW) distributed feedback (DFB) waveguide laser based on a symmetric periodically sampled grating fabricated in Yb-doped phosphate glass, using the femtosecond laser direct-write technique. The experimental results show that the peak spacing must be larger than 10 nm for stable operation. For improvement of the lasing performance, an asymmetric sampled grating structure is proposed such that a DW-DFB waveguide laser with 40 pm peak spacing is possible.
