We show theoretically that for a two-photon photosensitivity process a channel waveguide can be self-written in a planar slab of photosensitive germanosilicate glass. We further analyze features of this process using both numerical and analytical techniques and compare waveguides formed by this two-photon process to those formed by a one-photon process.
