    Abstract

    Resonator is one of the main component of almost any optoelectronic and photonic device. Quality (Q) factor is the most important characteristic of the resonator showing its ability to amplify the external electromagnetic field. There are a lot of types of optical resonator, e.g., photonic crystal cavities, Fabry-Perot resonators, whispering gallery mode resonator and many others. The high record values of Q factor today rich giant values up 1010. However, decrease of the size of any named above resonators results in exponential drop of their Q factor. When the size of the resonator is comparable with vacuum wavelength (the case of the lower Mie-resonance), the value of Q-factors is about 10-20, which is not enough for many practical applications. Therefore, the quest for compact photonic systems makes a new query for small high-Q resonators, using fundamentally new principles of light trapping.
