Journal ArticleDOI
Ultrafast optical switching in three-dimensional photonic crystals.
Dmitry A. Mazurenko,Robert Kerst,Jaap I. Dijkhuis,A. V. Akimov,Valery G. Golubev,D. A. Kurdyukov,Alexander B. Pevtsov,A. V. Sel’kin +7 more
TL;DR: The first experimental investigation of ultrafast optical switching in a three-dimensional photonic crystal made of a Si-opal composite is presented and results are analyzed within a model based on a two-band mixing formalism.
Journal ArticleDOI
Hypersonic Modulation of Light in Three-Dimensional Photonic and Phononic Band-Gap Materials
A. V. Akimov,Yukihiro Tanaka,Alexander B. Pevtsov,S. F. Kaplan,Valery G. Golubev,S. Tamura,Dmitri R. Yakovlev,Manfred Bayer +7 more
TL;DR: These studies show that light with energies close to the photonic band gap can be efficiently modulated by hypersonic waves.
Journal ArticleDOI
Phase transition-governed opal–VO2 photonic crystal
Valery G. Golubev,V. Yu. Davydov,N. F. Kartenko,D. A. Kurdyukov,A. V. Medvedev,Alexander B. Pevtsov,Alexey V. Scherbakov,E. B. Shadrin +7 more
TL;DR: In this paper, the opal and VO2 photonic crystals were prepared by the chemical bath deposition technique and the x-ray diffraction and Raman spectroscopic data confirm the crystalline perfection of VO2 impregnated into synthetic opal pores.
Journal ArticleDOI
Bragg reflection spectroscopy of opal-like photonic crystals
G. M. Gajiev,Valery G. Golubev,D. A. Kurdyukov,A. V. Medvedev,Alexander B. Pevtsov,A. V. Sel’kin,V. V. Travnikov +6 more
TL;DR: In this paper, the Bragg reflection spectra of photonic crystals based on synthetic opals were studied and a theoretical approach to the reflectance spectrum analysis was developed on the assumption of a planar spatially periodic medium, accounting for the effects of sintering of opal spheres and their uniaxial strain.
Journal ArticleDOI
Ultrafast stop band kinetics in a three-dimensional opal- V O 2 photonic crystal controlled by a photoinduced semiconductor-metal phase transition
Alexander B. Pevtsov,D. A. Kurdyukov,Valery G. Golubev,A. V. Akimov,A. A. Meluchev,A. V. Sel’kin,A. A. Kaplyanskii,Dmitri R. Yakovlev,Manfred Bayer +8 more
TL;DR: In this paper, the temporal evolution of the photonic stop band shift governed by the photoinduced phase transition in a three-dimensional photonic crystal based on opal-vanadium dioxide has been studied.
