S. Brunner et al., WAVE-GUIDING STRUCTURES IN POLYMERS BY ION-IMPLANTATION, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 89(1-4), 1994, pp. 373-378
Optical waveguides have been produced by ion irradiation of the surfac
e of polymer blocks of poly-(methyl-meth-acrylate) (PMMA). ion energie
s in the range of keV and MeV have been used. Mask construction is des
cribed. Strip waveguides, branches and Mach-Zehnder interferometers we
re generated. The refractive index as a function of the depth will be
discussed.
