Abstract

A waveguide laser with a neodymium-doped silica core is fabricated on a silicon substrate by a combination of flame hydrolysis deposition, solution doping, and direct UV writing. The neodymium-ion concentration is estimated to be ~8000 parts in 106. The propagation loss around 1.05 µm is < 0.8dB/cm. Lasing in the range 1048-1056 nm and 1356 ± 1 nm is observed. A slope efficiency of 33% for a high-reflectivity output coupler and a threshold of 4 mW of absorbed power for a 25% output coupler are measured for the 4F3/2 <--> 4I11/2 transition.
