Integrated photonic devices in organic media for optical networks — •Christian Stark, Jens Adams, Jonas Gortner, and Susanna Orlic — Optical Technologies Lab, Technische Universität Berlin

Integrated photonic devices represent an essential part of modern network technology. Photosensitive organic materials provide a powerful and flexible solution to build these devices. Compact de/multiplexers for WDM can be created by combining waveguides with holographic grating filters. We compare different approaches to writing waveguides for operation in the single mode regime. Methods to maximize the field overlap within the fiber are investigated in order to minimize coupling losses. Increasing integration of network systems demands continuous shrinking of individual devices. Thus we look for possibilities of decreasing bending losses. Waveguides with different geometries and refractive index profiles are analyzed in terms of field distribution, coupling and bending losses. Holographic WDM filters are created by transferring an interference patterns created by two laser beams into a periodic index modulation of a photopolymer bulky sample. We show filter characteristics of holographic gratings and discuss their applicability in WDM networks.
