Abstract
Microstructured fibers offer the possibility of being filled with unconventional
materials in order to influence the propagation properties in an optical fiber
waveguide. We have studied the filling of microstructured silica fibers with
electro-optic polymers. For this purpose a new electro-optic polymer formulation
has been developed which is well suited for the complete filling of capillaries
in microstructured optical fibers. Such filling could be of special interest
for all-solid bandgap fibers thanks to the high refractive index of electro-optic
polymers compared with silica, for fiber integrated electro-optical modulation,
or for tunable fiber Bragg gratings. We demonstrate waveguiding with such
filled fibers, investigate the integration of electrodes for poling and prove
the possibility of long-period grating inscription in such fibers.
