Electrical tuning of the LC:PDMS channels
In this paper, studies are presented on electrical tuning of optical channels formed by the PDMS-based waveguides infiltrated with a liquid crystalline material. In particular, preliminary results are demonstrated of numerical simulations demonstrating changes in optical parameters of the waveguide channels when influenced by electric field applied via flat and IPS electrodes in order to fabricate photonic switches based on optical directional couplers. The first experimental trials of sputtering the ITO layer on PDMS substrate are also shown.
