Abstract
We describe fabrication process of optical waveguide structures such as multi-mode optical splitter and optical waveguide with surface Bragg grating in polydimethylsiloxane (PDMS). Technology based on drawing of thin photoresist fiber with diameter up to 100 μm was developed and optimized. In this way, fibers drawn from photoresist form cores of waveguides in PDMS slab. After removal of the photoresist, created air channels can be filled in with different liquids. We prepared multimode waveguide structures in PDMS composed of two PDMS materials with different refractive indices. Using this technology, also complicated waveguide structures were prepared as optical splitter and surface Bragg grating were prepared in PDMS material.
