consider an optical fiber having a core index of 1.46 and a cladding index of 1.45. a) What is the critical angle for this core-cladding interface? B) for what range of angles inside the fiber at the entrance to the fiber will light totally internally reflected at the upper edge of the fiber? C) to what range of incidence angles does this correspond? D) how will that range of incidence angles in part C be changed if the fiber is submersed in water rather than air?

Refractive index of core of an optical fibre is 1.46 and its diameter is 250μm. Light propagates along the axis of the fibre . If the fibre bends at one point with radius of curvature R, Calculate the minimum value (critical radius of curvature Rmin) to sustain the light inside, without escaping from the fibre. Discuss the factors on which the critical radius of curvature may depend? Does it depend on the colour of light propagating through the fibre? ...

Optical engineers need to know the cone of acceptance of an optical fiber. This is the maximum angle that an entering light ray can make with the axis of the fiber if it is to be guided down the fiber. What is the cone of acceptance of an optical fiber for which the index of refraction of the core is 1.75 while that of the cladding is 1.55? You can model the fiber as a cylinder with a flat entrance...
