Abstract
In this paper low driving power linear and nonlinear optical waveguide devices using nematic liquid crystals as core are reported. Experiments and simulations show their behavior either as variable optical attenuators or as optical switches with extinction ratio in excess of 40 dB. All-optical modulation and switching is also shown using mW range optical power. © 2011 Ecole Polytechnique de Mo.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
