We describe the fabrication of integrated optical Bragg grating reflectors in organic waveguides, utilizing a DANS side-chain substituted polymer. The devices operate in the 1500 nm telecommunication window, and exhibit a linear narrow-band filtering action with good throughput and coupling efficiency. The effect of a small slant in the channel direction is also investigated experimentally. The structures have also been switched from a low to a high transmission state via a thermal refractive nonlinearity.
