Abstract
We describe different types of photonic structures that allow tunability of the photonic band gap upon the application of external stimuli, as the electric or magnetic field. We review and compare two porous one-dimensional (1-D) photonic crystals: in the first one, a liquid crystal has been infiltrated in the pores of the nanoparticle network, whereas in the second one, the optical response to the electric field of metallic nanoparticles has been exploited. Then, we present a 1-D photonic crystal made with indium tin oxide (ITO) nanoparticles, and we propose this system for electro-optic tuning. Finally, we describe a microcavity with a defect mode that is tuned in the near-infrared by the magnetic field, envisaging a contact-less magneto-optic switch. These optical switches can find applications in information and communications technologies and electrochromic windows.
