Abstract:
It is shown for the first time that multilayer periodic BaTiO$_{3}$/SiO$_{2}$ structures formed by the sol-gel method are tunable photonic crystals with dependence of the photonic band gap from the temperature of the sample. The shift of the minimum in the reflection spectrum in the photonic band gap is observed from 616 to 610 nm in the sample-temperature range from +184 to +24$^\circ$C, respectively, and is reproduced for several samples synthesized at a temperature of 450$^\circ$C.
Keywords:
sol-gel, barium titanate, tunable photonic crystal.
