Method and apparatus for suppressing stimulated brillouin scattering in fiber links

A laser comprising:

• a base;
• a gain medium operatively coupled to the base, having front and rear facets, to produce an optical emission in response to an electrical input;
• a reflective element, operatively coupled to the base, to form a laser cavity having endpoints defined by the front facet of the gain medium and a face of the reflective element;
• an optical path length adjustment element operatively coupled to the base;
• and
• a controller to provide an excitation input to the optical path length adjustment element to induce a modulation of an optical path length of the laser cavity to produce a laser output having a line width and modulation frequency for suppressing stimulated Brillouin scattering in a fiber link to which the laser output may be launched into.

A laser comprising:

• a gain medium to generate an optical emission;
• first and second reflective elements, to define a laser cavity;
• first means for adjusting an optical path length of the laser cavity;
• and
• controller means to provide an excitation single to the first means for adjusting the optical path length to induce a modulation of the optical path length of the laser cavity to produce a laser output having a line width and modulation frequency for suppressing stimulated Brillouin scattering in a fiber link to which the laser output may be launched into.
