    Notes: [Auszug] Light travels at a speed c of 300 million metres per second in a vacuum, but can be slowed down to cycling speed (around 17 metres per second) or can even be brought to a halt, when the right medium is used. Although we may not see commercial applications appearing immediately, there is a clear ...

    Notes: [Auszug] Oceanic rogue waves — monstrous sea waves that form spontaneously and can reach up to 30 metres in height — have been held responsible for marine misfortunes ranging from the sudden sinking of seagoing ships to damage to oil platforms. They are not just the stuff of maritime folklore ...

    Notes: This letter describes a fiber Bragg grating device that has tunable chirp. It relies on a distributed on-fiber resistive heater that consists of a thin metal film deposited onto the outer surface of a bare fiber; the thickness of this film varies continuously with position along the fiber. The physics of heat flow and diffusion in these structures leads to temperature gradients that follow, to a remarkably good approximation, the local resistance of the tapered metal film. This temperature distribution produces a chirp with a geometry that is defined by the thickness profile of the film and at a rate that can be adjusted by changing the current. Finite element modeling illuminates aspects of the flow of heat in these structures, and optical measurements demonstrate important characteristics of the devices. © 1999 American Institute of Physics.
