Therefore, (nonlinear) photonic crystal properties can be attributed to purple membrane patches of bacteriorhodopsin. This is an important finding, since this natural material exhibits photonic bandgap properties without careful and costly engineering, but through self-assembly. In...

In the two previous subsections, I have presented design strategies for the SPR sensors based on photonic crystal Bragg fibers. In principle, any photonic bandgap fiber can be used in place of a Bragg fiber to develop such sensors. In this section, I present an example of a SPR sensor based on a solid-core honeycomb PCF. 

Three-dimensional opal-VO based photonic crystals were prepared by the chemical bath deposition technique. The x-ray diffraction and Raman spectroscopy confirm the crystalline perfection of VO2 impregnated into synthetic opal pores. It is shown from the optical reflectivity measurements that the photonic bandgap of the opal-V02 based photonic crystals composite is governed by the phase transition in VO2. The shift of Bragg diffraction spectra under the pulsed (10 ns) illumination of YAG.Nd laser has been also observed in the opal-VO2 composites.
