Abstract
We report the performance of a dual-wavelength waveguide laser based on a phase-modulated sampled-grating architecture fabricated using the femtosecond laser direct-write technique. The waveguide laser was written in Yb-doped phosphate glass and had a narrow linewidth (), high signal-to-noise ratio (), 5 mW output power per channel, and wavelength separation of 10 nm.
