    Fast one-dimensional photonic crystal modulators for the terahertz range

  • Original language description

    Optically controlled one-dimensional photonic crystal structures for the THz range are studied both theoretically and experimentally. A GaAs:Cr layer constitutes a defect in the photonic crystals studied; its photoexcitation by 800 nm optical femtosecondpulses leads to the modulation of the THz beam. Optimum resonant structures are found, constructed and experimentally studied. The time response of the structures studied is shorter than 330 ps.

    Rychlé opto-terahertzové modulátory na bázi fotonických krystalů pro terahertzovou oblast

  • Czech description

    Teoreticky i experimentálně jsme studovali optické spínání jednodimenzionálních fotonických struktur pro terahertzovou oblast. Jako tzv. defektní vrstvy jsme ve fotonických krystalech použili tenké GaAs:Cr destičky; jejich excitace femtosekundovými optickými pulsy u 800 nm vede k modulaci intensity terahertzového svazku. Navrhli jsme a prostudovali optimální rezonanční struktury, jejich časová odezva je kratší než 330 ps.
