Femtosecond holography in lithium niobate crystals [PDF]

Optics Letters, 2005
Spatial gratings are recorded holographically by two femtosecond pump pulses at 388 nm in lithium niobate (LiNbO3) crystals and read out by a Bragg-matched, temporally delayed probe pulse at 776 nm. We claim, to our knowledge, the first holographic pump-probe experiments with subpicosecond temporal resolution for LiNbO3.

Optically Defined Reconfigurable THz Metasurfaces using Graphene on Iron‐Doped Lithium Niobate

Advanced Photonics Research, 2022
Graphene plasmonic devices have been demonstrated to show great potential for reconfigurable metasurfaces due to the tuneable electronic charge transport properties of graphene in response to electrostatic gating.

Elimination of the chirp of optical pulses through cascaded nonlinearities in periodically poled lithium niobate waveguides

, 2010
We propose and demonstrate a novel method for the elimination of arbitrary frequency chirp from short optical pulses. The technique is based on the combination of two cascaded second-order nonlinearities in two individual periodically poled lithium ...

Operation of Holographic Elements with Broadband Light Sources [PDF]

, 2005
This thesis presents the theoretical and experimental investigation of volume holography operated with broadband/polychromatic light sources, i.e., in both continuous-wave (linear) and femtosecond-pulse (nonlinear) regimes.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Enhanced photorefractive properties of indium co-doped LiNbO3:Mo crystals

AIP Advances, 2018
We grew a set of indium and molybdenum co-doped lithium niobate crystals with various indium doping concentrations and investigated their photorefractive properties at different wavelengths (442, 488 and 532 nm).

Technology for creating a photonic integrated circuit on a lithium niobate substrate

Компьютерная оптика
We propose a new technology for manufacturing a photonic integrated circuit (PIC) on a lithium niobate substrate. It is shown that there is no need to dope the top layer of lithium niobate to create a waveguide system and control radiation.
