Abstract

We investigate an impact of a small particle located on the surface of a fiber resonator on the dynamics of the whispering gallery modes (WGM) circulating near the fiber surface. We consider a single molecule of fibrinogen and bovine serum albumin that is put in contact with the surface of the fiber. We have studied both temporal dynamics of optical pulses propagating at the WGM as well as changes in the spectrum of WGM due to impact of the particle.
