High-Performance Integrated Erbium -Ytterbium Codoped Glass Waveguide Laser

We report the design and characterization of an efficient erbium -ytterbium codoped ion exchanged glass dis- tributed Bragg reflector (DBR) laser pumped by a 980-nm pig- tailed laser source. Laser oscillation at 1536 nm is demonstrated with a pump threshold of 35 mW and a slope efficiency of 10.6%. The dependence of lasing performance on pump wavelength detuning is examined for different cavity designs.
