Paper Abstract

Tunable waveguide Bragg gratings were demonstrated in PYR-3 chromophore doped polymers. We report on the fabrication and the performance of the device. Polycarbonate thin films were doped with PYR-3 (2-{3- Cyano-4- [3-(1-decyl-1 H-pyridin-4-ylidene)-propenyl]-5,5-dimethyi-5 H-furan-2-ylidene}-malononitrile) chromophore, consisting of a dihydropyridinylidene donor and three carbon atoms in the conjugated linker between donor and acceptor. Ridge waveguides were laser micro-machined into the polycarbonate film with a JPSA micromachining system equipped with a KrF excimer laser at 248 nm. Bragg gratings were inscribed into the waveguide by permanently photobleaching the PYR-3 chromophores using a phase mask to achieve narrowband reflections at wavelengths around 1550 nm. Electro-optic properties were introduced by contact poling. Applying a static external electric field leads to the shift of the reflection peak.
