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 $\sim 8000$ parts in ${10}^6$. The propagation loss around $1.05 \mathit{\mu }\mathrm{m}$ is $<0.8 \mathrm{dB}/\mathrm{cm}$. Lasing in the range 1048–1056 nm and $1356\pm 1 \mathrm{nm}$ 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 ${{}^{4}F}_{3/2}\to {{}^{4}I}_{11/2}$ transition.
