A focused 750 keV proton microbeam was used to fabricate an embedded Mach-Zehnder (MZ) optical waveguide in a polydimethylsiloxane (PDMS) film for interferometer application. The sample position was precisely controlled by a mechanical stage together with scanning microbeam to form an embedded MZ waveguide structure within an area of 0.3 mm × 40 mm. The MZ waveguides with core size of 8 μm was successfully embedded in PDMS film at a depth of 18 μm by 750 keV proton microbeam with fluences from 10 to 100 nC/mm2. The MZ waveguides were coupled with an IR fiber-laser with a center wavelength of 1550 nm and evaluated by using the transmitted intensity images from an IR vidicon camera. The results indicate that the embedded MZ waveguide structure in PDMS achieved single spot light propagation, which is necessary for building optical switching circuits based on polymer MZ waveguides.
