“…In this case the loss value for one axis is about α x = -10*log (I(x)). For fully identical mode fields we insert for I(x) a Gaussian function as written in formula (7). The calculated loss depending on a geometrical axis shift in one direction is shown in Fig.…”

Integrated optic single mode waveguides in polymer substrates are of interest for several applications especially in the visible wavelength range e.g. to build waveguide components for biophotonic, sensors or passive splitters. The manufacturing process contains DUV or UV lithography and some different pre or post exposure bakes depending on the used type of polymer. Chromium masks offer facile and controllable processing and rapid exposure times. Surface waveguides can be covered with an index matched cladding substrate on top to get buried light guiding. The end faces and also the over all thickness of about 1 mm of the component packages gives the possibility for a stable coupling between fiber arrays and planar waveguide substrates.The paper describes the results of a single mode field analysis and the experimental adjustment of polymer waveguides for wavelengths within the visible range of light to achieve low coupling losses. Some different manufacturing process steps are compared depending on the used polymer material. A comparison between the measured waveguides and fiber mode near field diameters and the nominal calculated numerical apertures are presented. The different insertion loss is measured and illustrated as well.
