Electro-optic and magneto-optic photonic devices based on multilayer photonic structures
Journal of Photonics for Energy, 2018 In this work 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 1D photonic crystals: in the first one a liquid crystal has been infiltrated in the pores of the nanoparticle network, while in the ...
