Dual-core optical fiber as beam splitter with arbitrary, tunable polarization-dependent transfer function

Dual-core optical fiber as beam splitter with arbitrary, tunable polarization-dependent transfer function
Dual-core optical fiber as beam splitter with arbitrary, tunable polarization-dependent transfer function
We present the design of a microstructured dual-core optical fiber with integrated electrodes and filled with liquid crystals. The dual-core structure acts as a directional coupler whose properties depend on the liquid crystal alignment. We show that with four electrodes and two separate driving voltages below 30 V on the electrodes, the beam-splitting properties of the fiber can be controlled independently and continuously for the two polarization components, thus allowing for the realization of any arbitrary 2x2 transfer function, such as tunable polarizers, polarization-dependent attenuators, or polarization-independent beam splitting.

Abstract

We present the design of a microstructured dual-core optical fiber with integrated electrodes and filled with liquid crystals. The dual-core structure acts as a directional coupler whose properties depend on the liquid crystal alignment. We show that with four electrodes and two separate driving voltages below 30 V on the electrodes, the beam-splitting properties of the fiber can be controlled independently and continuously for the two polarization components, thus allowing for the realization of any arbitrary 2x2 transfer function, such as tunable polarizers, polarization-dependent attenuators, or polarization-independent beam splitting.
