摘要

The ultraviolet (UV) photosensitivity of Ta₂O₅ measured in a rib waveguide Mach-Zehnder interferometer (MZI) is reported. With a cumulative fluence of 72 J/cm² at a wavelength of 248 nm incident upon one arm through a 3-mm-long window, the MZI exhibits a phase shift of 8π radians at wavelength λ = 1.55 μm, corresponding to a saturated refractive index change of 2.1 × 10^-3. Real time measurements of the MZI output during exposure are given and the UV-induced refractive index change is found to be negative.
