个人简介
These special excitations of light have very special properties and are extremely useful for various applications. Prof. Deych's research interests lie in application of these modes in biosensing, where the goal is to develop a sensor capable of detecting viruses or other biological objects. The unique ability of WGMs to detect small particles and even single molecules results from two important characteristics of these modes. First, they produce extremely narrow lines in the spectrum of light scattered from the resonators. As a result, even very small shifts of these lines can be spectrally resolved. Second, the field of these modes is concentrated in the vicinity of the resonator's surface, where it is strongly enhanced. This enhancement of the field amplifies effects of smallest changes in the environment, such as adsorption of a virus to the surface of the resonator, resulting in observable shifts of the spectral lines.
Another aspect of the Whispering Gallery Modes studied by Prof. Deych and his students is concerned with mechanical action of light. It has been well known for a long time that light can produce mechanical forces on polarizable dielectrics. Prof. Deych's research showed that confining light within WGM resonators significantly changes these forces and give them new unexpected characteristics. Prof. Deych studies how these changes can be exploited for optical manipulation of small objects and optical cooling.
