While single-mode semiconductor lasers have various advantages, one disadvantage is their great sensitivity to optical feedback. Even small amounts of reflected light can have a destabilizing effect, ...

Fiber Bragg gratings (FBGs) in single-mode fibers, used as narrowband filters, have reached a high maturity level, especially for applications in telecommunications and sensing. In spectroscopic ...

Recent progress on low-bending-loss single-mode optical fibers for fiber-to-the-home (FTTH) is reviewed. Designing and manufacturing for three types of fibers-a step-index-profile fiber, a ...
