Area of Science:

  • Materials Science
  • Optoelectronics
  • Soft Matter Physics

Background:

  • Periodic structures in optical fibers are crucial for applications like fiber Bragg gratings (FBGs) and long-period fiber gratings (LPFGs).
  • Liquid crystal (LC)-based composites offer tunable optical properties, but their integration into stable periodic structures requires advanced fabrication methods.
  • Natural self-assembly processes, like nematic-isotropic phase separation, can simplify the production of complex photonic structures.

Purpose of the Study:

  • To investigate the behavior of polymer-stabilized liquid crystal (LC)-based self-assembled periodic structures under an external electric field.
  • To analyze the reorientation dynamics of LC molecules within these structures when subjected to electric fields applied orthogonally.
  • To evaluate the potential of these structures for use in optical sensing applications.

Main Methods:

  • Fabrication of polymer-stabilized LC-based periodic structures using nematic-isotropic phase separation in a 1D confined space.
  • Application of external electric fields in two orthogonal directions to induce reorientation of LC molecules.
  • Analysis of structural period, defect formation, and effective birefringence changes in response to the electric field.
  • Optical characterization to assess changes in spectral properties.

Main Results:

  • The period of the polymerized structure remained constant during LC reorientation under an electric field.
  • The electric field induced new periodic defects in the LC orientation, leading to significant changes in effective birefringence.
  • The observed changes in birefringence were dependent on the direction of the applied electric field vector.
  • The structure exhibited drastic changes in effective birefringence, confirming its responsiveness to electric fields.

Conclusions:

  • Polymer-stabilized LC self-assembled periodic structures offer a promising route for creating tunable photonic devices.
  • The electric field-induced reorientation and subsequent birefringence changes highlight their potential as active optical components.
  • These structures show significant promise for applications as voltage or electric field sensors, functioning as LPFGs or FBGs in the visible and near-infrared regions.
