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
Subpicosecond shifting of the photonic band gap in a three-dimensional photonic crystal
Dmitry A. Mazurenko,Robert Kerst,Jaap I. Dijkhuis,A. V. Akimov,Valery G. Golubev,A.A. Kaplyanskii,D. A. Kurdyukov,Alexander B. Pevtsov +7 more
TL;DR: In this article, a three-dimensional photonic crystal was demonstrated to shift from the semiconductor to the metallic phase of VO2 in the pores of an artificial silica opal in a time of less than 350fs.
Journal ArticleDOI
Femtosecond Bragg switching in opal-a-nc-Si photonic crystals
Dmitry A. Mazurenko,Robert Kerst,A. V. Akimov,Alexander B. Pevtsov,D. A. Kurdyukov,Valery G. Golubev,Alexander V. Sel'kin,Jaap I. Dijkhuis +7 more
TL;DR: In this paper, the authors demonstrate ultrafast all-optical switching in a three-dimensional photonic crystal made of an opal-silicon composite and show that the switching-on time is faster than 30 fs and determined by the pump pulse duration.
Proceedings ArticleDOI
Ultrafast Bragg switching induced by a phase transition in a 3D photonic crystal
Dmitry A. Mazurenko,A. V. Akimov,Valery G. Golubev,A.A. Kaplyanskii,D. A. Kurdyukov,Alexander B. Pevtsov,Robert Kerst,Jaap I. Dijkhuis +7 more
TL;DR: In this paper, an ultrashort 120-fs laser pulse induces a phase transition in vanadium dioxide filling the pores of an artificial silica opal, thus changing the effective dielectric constant of the opal.
