We present a laser-tuned WGM microresonator integrated with EO-doped PVA coating.
The WGM resonance wavelength is sensitive to applied 532 nm laser power density.
An optimal EO weight percentage is acquired for fully linear wavelength tuning.
The microresonator shows good spectral reversibility under 532 nm laser excitation.
The microresonator exhibits good dynamic performance for slow signal modulation.
