Femtosecond-laser inscribed, tunable, waveguide embedded Bragg gratings in lithium niobate

We demonstrate electro-optical tunable Bragg gratings embedded into complex two-dimensional waveguides in lithium niobate by femtosecond direct laser writing. The structures support both, ordinary and extraordinary guiding and narrowband reflections around λ = 1.55 μm.
