We report on a novel fabrication technology for building a waveguide system with its core and cladding both formed by Polydimethylsiloxane (PDMS). The refractive index difference is realized by controlling the mixing ratio of base and curing agent. The entire process only requires regular PDMS material and is completely compatible with soft lithography process. The experimental results show a good confinement of light and the transmission loss was about 1.1 dB/cm at 460 nm. (C) 2013 Elsevier B.V. All rights reserved.
