In this work we describe different types of photonic structures that allow\ntunability of the photonic band gap upon the application of external stimuli,\nas the electric or magnetic field. We review and compare two porous 1D photonic\ncrystals: in the first one a liquid crystal has been infiltrated in the pores\nof the nanoparticle network, while in the second one the optical response to\nthe electric field of metallic nanoparticles has been exploited. Then, we\npresent a 1D photonic crystal made with indium tin oxide (ITO) nanoparticles,\nand we propose this system for electro-optic tuning. Finally, we describe a\nmicrocavity with a defect mode that is tuned in the near infrared by the\nmagnetic field, envisaging a contact-less magneto-optic switch. These optical\nswitches can find applications in ICT and electrochromic windows.\n
