Squeezing Alters Frequency Tuning of WGM Optical Resonator

advertisement:

Tuning rates for modes of different indices can be made to differ.

Mechanical squeezing has been found to alter the frequency tuning of a whispering-gallery-mode (WGM) optical resonator that has an elliptical shape and is made of lithium niobate. It may be possible to exploit this effect to design reconfigurable optical filters for optical communications and for scientific experiments involving quantum electrodynamics.
