title: Effect of strain in periodically deformed single-mode optical fibers.
abstract: The effect of periodic strains in single-mode fibers, which lead to periodic changes of the relative index of refraction, is studied theoretically and experimentally. The main effect of the periodic strain is to downshift the beat length between the optical modes in the fiber.
