Area of Science:

  • Optics and Photonics
  • Materials Science

Background:

  • Terahertz (THz) technology requires versatile optical components.
  • Tunable filters are crucial for THz spectroscopy and imaging.
  • Existing THz filters often lack broad tunability or require complex mechanisms.

Purpose of the Study:

  • To demonstrate a broadly tunable terahertz Solc-type birefringence filter.
  • To investigate the use of magnetically controlled nematic liquid crystals for THz wave manipulation.

Main Methods:

  • Fabrication of a Solc-type filter incorporating nematic liquid crystals.
  • Application of magnetic fields to control birefringence in the liquid crystal.
  • Characterization of the filter's transmission spectrum and tunability.

Main Results:

  • Achieved continuous tuning of the central passband frequency from 0.176 to 0.793 THz.
  • Demonstrated a broadly tunable terahertz filter with a Solc-type architecture.
  • Measured an insertion loss of approximately 5 dB for the device.

Conclusions:

  • Magnetically controlled birefringence in nematic liquid crystals offers an effective method for broad THz frequency tuning.
  • The developed Solc-type filter presents a promising solution for tunable THz applications.
  • The device exhibits practical performance with a reasonable insertion loss.
