REALIZATION OF INTEGRATED BRAGG REFLECTORS IN DANS-POLYMER WAVE-GUIDES

We describe the fabrication of integrated optical Bragg grating reflec tors in organic waveguides, utilizing a DANS side-chain substituted po lymer. The devices operate in the 1.5 mum telecommunication window, an d exhibit a linear narrow-band filtering action with good throughput a nd coupling efficiency. The effect of a small slant in the channel dir ection is also investigated experimentally. The structures have also b een switched from a low to a high transmission state via a thermal ref ractive nonlinearity.
