Abstract

An integrated electro-optic waveguide modulator is demonstrated in bulk fused silica. A Mach–Zehnder interferometer waveguide structure is fabricated by direct writing with a femtosecond laser followed by thermal poling. A 20° electro-optic phase shift is achieved at an operating wavelength of $1.55\mu \mathrm{m}$ with an applied voltage of 400 V and an interaction length of 25.6 mm, which correspond to an estimated effective electro-optic coefficient of $0.17\mathrm{pm}∕\mathrm{V}$ for the TE-polarized mode.
