We report what is to our knowledge the first demonstration of electro-optic phase modulation in a fused-silica channel waveguide. The no linearity is induced through elevated temperature poling of an electron-beam-irradiated waveguide. A phase shift of 32 mrad was measured at λ = 633 nm for a device interaction length of 4.8 mm and an applied electric field of 7.3 V/μm.
