Development of One-Dimensional Dielectric and Metal-Dielectric Photonic Band Gap for Optical Switching and Limiting Applications

Abstract

We investigated a newly synthesized bis-phenylazo derivative, namely bis-perfluoroalkylsulfonylamino-arylazomethylene-triphenyl-phosphorane (BAM-TPP). Azobenzenes constitute a class of conjugated organic materials that have received considerable attention for their reversible photochromism and remarkable second order nonlinear optical (NLO) properties. These photochemical/physical properties, combined with the ability of varying their chemical structure with the wavelength of the incident light, make azobenzenes particularly attractive candidates for applications like optical data storage, optical switching and liquid crystals technology. Specifically, some azobenzenes may intercur a photoisomerization from a cis- to a trans- cofiguration under UV illumination, and vice versa. The two configurations correspond to different values of optical absorbancy, thus being interesting for optical switching applications.
