摘要： This invention relates to a method of creating an index grating in an optical fiber comprising disposing a slit mask containing one or more slits over a side of an optical fiber, illuminating the fiber through the slit mask by substantially monochromatic ultraviolet light for a short interval, whereby an index grating line is created and stored in the core of the fiber.

摘要： A fused twin biconical taper fiber optic splitter comprised of a pair of non-identical monomode or nominally monomode optical fibers having predetermined cladding diameters fused at respective narrowed waists, the cladding diameter of one fiber before coupler fabrication being greater than the other, whereby wavelength selective coupling between one and the other fiber is obtained.

摘要： A method of forming a single mode biconical fiber optic coupler comprising holding 2 or more optical fibers parallel to and in contact with each other at spaced apart locations, exerting equal tension in opposite directions to the fibers at said spaced apart locations to stretch the fibers, fusing the fibers over a waist region, and scanning the tip of a flame from a microtorch back and forth along the fibers at a speed which is at least five times the speed of stretching of the fibers. This results in an overcoupled low loss coupler, a pressure or a temperature sensor, comprised of at least a pair of monomode optical fibers fused and parallel at a stretched waist portion, each having biconical tapers at opposite ends of the waist portion, the coupler having exhibited at least about 500 power transfer cycles during stretching formation of the waist portion.
摘要翻译：一种形成单模双锥形光纤耦合器的方法，包括在间隔开的位置处彼此保持平行于或相互接触的2根或更多根光纤，在所述间隔开的位置处向与纤维相反的方向施加相等的张力以拉伸纤维，将纤维熔合在腰部区域上，并且以至少是纤维拉伸速度的五倍的速度沿着纤维来回扫描来自微弧的火焰的尖端。这导致了过耦合的低损耗耦合器，压力或温度传感器，由至少一对在拉伸的腰部处熔合和平行的单模光纤组成，每对光纤在腰部的相对端具有双锥形锥形，耦合器具有在拉伸形成腰部期间展现出至少约500次功率传递循环。

摘要： The coupler consists of an intermediate finite length waveguide located between a first and at least one second waveguide with the refractive index of the intermediate waveguide being greater than the refractive indices of the other waveguides. The intermediate waveguide further includes a structure which either in a fixed manner as by a surface relief, or in a controlled manner--as by electro-optic or acousto-optic perturbation, produces modes of propagation in the intermediate waveguide for a preselected frequency, such that energy may be coupled to or from the waveguides to the intermediate waveguide by mode matching and this energy may be converted from one mode to another in the intermediate waveguide.
