Poling of a channel waveguide.
This paper describes thermal poling of a silica based channel waveguide Mach-Zehnder interferometer, and direct measurent of the dc-Kerr and induced electro-optic coefficients. A /(3) of 5.2 (+/-0.4) x 10-22 (m/V)2 was measured for the un-poled waveguide, and r-coefficient of approximately 0.07 pm/V was induced by poling. /(3) increased by a factor of 1.9 after poling. It is shown that the dc-Kerr effect plays an important role in the poled device.
