ABSTRACT
This chapter describes the state of the art of device development, lifetime and performance testing, standards in preparation, and some future directions in the novel industrial field. It explores in detail the application of nanostructures in passive, fiber-optic (FO) power control, showing two already-fielded examples, namely, the optical fuse and limiter. Nanostructures are currently beginning to be used industrially as devices in FO telecommunications. Fiber lasers, FO communication systems, and other systems designed for light delivery, such as in medical, industrial, and remote sensing applications, often handle high power levels or high fluence, up to 1 W or more in a single-mode fiber or waveguide. Fiber lasers, FO communication systems, and other systems for light delivery, such as in medical, industrial, and remote sensing applications, often handle high levels of optical power or high fluence, namely, up to 1 W or more in a SMF or waveguide.
