TL;DR: In this article, high pressure "hydrogen loading" has been used to sensitise standard singlemode fibres, resulting in the largest reported UV induced index changes for low GeO/sub 2/ fibres.

TL;DR: A general criterion to describe this limitation that must be satisfied by all materials is derived and experimentally evaluated this criterion for a lead-glass fiber.

TL;DR: In this article, the optical properties of strong ( delta n/n approximately 10/sup -3/) in-core optical fiber phase gratings written by the UV laser sidewriting technique were measured and calculated.

TL;DR: A phenomenological treatment of surface second-harmonic generation that can be applied to a host of geometries of interest is presented in this paper, where the expressions for the surface secondharmonic generated power can all be written in one compact form, from which the dependence of the signal on polarization, angle of incidence, and other experimental parameters can be extracted.

TL;DR: The anisotropic nature of the UV-induced index change achieved in photosensitive optical fibers is characterized by a direct measurement of the induced birefringence in three different fibers.
