1 INTRODUCTION
In the present work, we review some of our efforts here at the Guided Wave Optics Laboratory (GWOL) related to the writing of holographical gratings in materials that are suited to fabrication of long lifetime electro-optic (EO) waveguide devices. We are motivated by the numerous examples of the profitable use of diffractive structures in waveguides. Fiber Bragg gratings are a prime example of the genre [1, 2]. Quasi-phase matching of χ(2) waveguides ...
