We present a theoretical analysis of the refractometric sensitivity of a spherical microresonator coated with a porous sensing layer performed for different whispering gallery modes. The effective refractive index of the modes is also calculated. The

Silica microspheres were coated with a porous silica layer. The wavelength shift of the whispering gallery modes of the coated microsphere was used to detect small traces of ammonia vapors. The sensing sensitivities of different modes of the same mic

Spherical microresonators have been used to measure small concentrations of ammonia vapors. By tracking the shift of a whispering gallery mode (WGM) frequency, we can detect small changes of the refractive index of the medium in which the WGM electri

Spherical microresonators based on whispering gallery modes (WGM) have been used for measuring the concentration of ammonia vapours. Because of their high Q-factors, the WGM microresonators are very sensitive to environmental conditions such as tempe

Evanescent waves propagating in optical fibers can collect and deliver information about absorption spectra of an external medium. We analyse peculiarities of evanescent modes and whispering gallery modes that can be excited in a single-index multimo

For the sensing application and investigating the nonlinear effects, microresonator structures are very suitable due to their enormous quality factor and small mode volume. These properties can be extended into the mid-infrared region by creating mic
