Abstract
Negative index grating growth in germanosilicate planar waveguides fabricat ed by hollow cathode(HC)-PECVD are characterised in detail. Differences in index modulation growth, both in terms of the grating strength and the rate of negative index change as a function of fluence, are observed. On the ot her hand, the average index change of the two polarisation states shows the same rate of growth revealing that grating growth is dependent on more tha n on index change triggered by simple isotropic uv-defect interactions.
