Abstract
The excitation of standing TM waves by a subwavelength slit in the single-mode waveguide resonator with the metallic borders is considered. In this structure, the input energy through the slit strongly depends on the incident wavelength. Consequently, the Q-factor of the system computed by the finite element method reaches the values of 104 in the near infrared region. The significant change of the scattered wave energy is achieved by the changing of dielectric constant value by 5 ×10−4 or the thickness of resonator by 0.5 nm. The sensitivity of system to the parameters of structure allows one to use the system in various applications such as devices of optical bistability, modulators, and optical sensors of vibration, displacement and temperature.
