Birefringent cadmium-telluride-based metamaterial

Birefringent cadmium-telluride-based metamaterial
Birefringent cadmium-telluride-based metamaterial
A CdTe-based optical metamaterial, with large induced optical birefringence (4%), has been produced and its optical properties fully characterized and modeled over the spectral range 1500- 450 nm. This metamaterial, which is related to mesoporous silica, is made using electrochemical deposition in the presence of a lyotropic liquid crystal template. This process produces a stoichiometric CdTe film containing a hexagonal array of similar to4.2 nm cylindrical pores with interpore separation similar to6.5 nm. A model of the dielectric properties of the films indicates that their birefringence can be entirely attributed to the film's nanoporosity.

Abstract

A CdTe-based optical metamaterial, with large induced optical birefringence (4%), has been produced and its optical properties fully characterized and modeled over the spectral range 1500- 450 nm. This metamaterial, which is related to mesoporous silica, is made using electrochemical deposition in the presence of a lyotropic liquid crystal template. This process produces a stoichiometric CdTe film containing a hexagonal array of similar to4.2 nm cylindrical pores with interpore separation similar to6.5 nm. A model of the dielectric properties of the films indicates that their birefringence can be entirely attributed to the film's nanoporosity.
