Abstract :
The fabrication of integrated optical Bragg grating reflectors in organic waveguides, utilizing a DANS (4-dialkylamino-4´-nitrostilbene) side-chain-substituted polymer is described. The devices operate in the 1.5-μm telecommunication window and exhibit a linear narrowband filtering action with good throughput and coupling efficiency. The effect of a small slant in the channel direction is investigated experimentally. The structures have also been switched from a low to a high transmission state via a thermal refractive nonlinearity
