Interfacial Engineering Approach to Pattern Resilient Polymer Photonic Crystals with Temperature‐Responsive Optical Properties

Optical properties of carbon nanofiber photonic crystals.

Carbon nanofibers (CNFs) are used as components of planar photonic crystals. Square and rectangular lattices and random patterns of vertically aligned CNFs were fabricated and their properties studied using ellipsometry. We show that detailed information such as symmetry directions and the band structure of these novel materials can be extracted from considerations of the polarization state in ...

Thickness Dependence of the Optical Properties of Ordered Silica-Air and Air-Polymer Photonic Crystals

We report observations of the optical stop band of periodic planar arrays of submicron silica spheres, and of macroporous polymers grown from these silica templates. The stop-band width and peak attenuation depend on the number of layers and on the dielectric contrast between the spheres and the interstitial regions, both of which are experimentally controlled. The results are compared to the p...

Sub-nanometer precision modification of the optical properties of three-dimensional polymer-based photonic crystals

We present a convenient post-fabrication technique to precisely tune the optical properties of polymer-based threedimensional photonic crystals with sub-nanometer precision. Conventional air-plasma etching is utilized to modify the filling fraction of direct laser written polymer photonic crystals beyond the wavelength-imposed limits. Tuning of the optical properties is monitored in transmissio...

Optical Properties of Antiferromagnetic/Ion- Crystalic Photonic Crystals

Influence of optical Kerr coefficient on photonic band structures of hexagonal-lattice function photonic crystals

In this paper, we have studied the photonic band structure of function photonic crystals in which the dielectric constant of the scattering centers (rods) is a function of space coordinates. The under-studied lattice is hexagonal and cross section of rods has a circular symmetry embedded in the air background. Photonic band structures for both electric and magnetic polarizations of the electrom...
