Abstract:Epsilon-near-zero (ENZ) materials have shown significant potential for nonlinear optical applications due to their extraordinary enhancement of optical nonlinearity. Our experiments show that poly(3,4-ethylenedioxythiophene) (PEDOT) films can be modified to boost their conductivity and exhibit ENZ wavelengths from mid-infrared to visible regimes. Degenerate optical nonlinearity coefficients of EG-modified PEDOT films with an ENZ wavelength of 1587 nm are enhanced at 1550 nm to be larger than those of most of t… Show more
This work introduces an angle-tunable polymeric photonic diode with enhanced light control by integrating it with a 1D photonic crystal. The diode's non-reciprocity can be controlled by changing the incident light angle.
We show that the n-type conducting polymer PBFDO can be optically metallic for wavelengths above around 695 nm after post-treatment, and that nanostructures of the material can act as optical nanoantennas that are dynamically switchable.
