Optoelectronic devices with liquid crystals and PDMS channels
We present optoelectronic tunable and switchable devices for integrated optics based on easy-to-build optical waveguides. The devices take advantage of the spontaneous homeotropically alignment of liquid crystals (LC) molecules to the surface of a polydimethylsiloxane (PDMS) microfluidic channel (LC:PDMS). This behaviour was investigated by means of Monte Carlo simulations, which allowed to evaluate the molecular organization and ordering inside the cell.
