Abstract
Wavelength tunability of whispering gallery modes (WGMs) excited in a cylindrical micro resonator based on a short section of polymer optical fiber (POF) under tensile strain is investigated. It is demonstrated that an increase in the axial strain applied to the POF micro resonator results in a liner blueshift of WGMs with a sensitivity of 0.66 pm/μɛ.
