We present several approaches to make integrated optic filters, which include either liquid crystals or composite structures including polymers. The presence of liquid crystals allows tunability of the filters controlled by means of low power electric signals. All-optical tuneable filters are also presented in which optical nonlinear properties of liquid crystals are deployed to drive the device.

Abstract
We present several approaches to make integrated optic filters, which include either liquid crystals or composite structures including polymers. The presence of liquid crystals allows tunability of the filters controlled by means of low power electric signals. All-optical tuneable filters are also presented in which optical nonlinear properties of liquid crystals are deployed to drive the device.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
