摘要：

The stress anisotropy in planar germanosilicate waveguides is used to follow the changes in stress, measured as a birefringence, with UV irradiation. Compressive stress increases with the growth of the negative index grating, saturating when the grating modulation saturates. (C) 1999 Optical Society of America.
