Abstract in brief

  • The study presents a tunable Fabry-Perot interferometer operating in the terahertz range, which uses pitch-variable subwavelength gratings to control the effective refractive index and shift the resonant frequency.
  • Unlike traditional tuning methods that involve filling materials or deforming the cavity, this approach achieves higher transmission and a better quality factor (Q-factor) by stretching the PVSWGs, allowing precise frequency tuning.
  • The device achieved a peak transmittance of 0.87, a Q-factor of 34, and a frequency shift of 17 GHz around 0.303 THz, making it promising for THz communications and adjustable wave band applications.]
