Electrically tunable Brillouin fiber laser based on a metal-coated single-mode optical fiber

We explore tunability of the Brillouin fiber laser employing Joule heating. For this purpose, 10-m-length of a metal-coated single-mode optical cavity fiber has been directly included into an electrical circuit, like a conductor wire. With the current up to ∼3.5A the laser tuning is demonstrated ove...

Summary:We explore tunability of the Brillouin fiber laser employing Joule heating. For this purpose, 10-m-length of a metal-coated single-mode optical cavity fiber has been directly included into an electrical circuit, like a conductor wire. With the current up to ∼3.5A the laser tuning is demonstrated over a spectrum range of ∼400MHz. The observed laser line broadening up to ∼2MHz is explained by frequency drift and mode-hoping in the laser caused by thermal noise.
