Squeezing Alters Frequency Tuning of WGM Optical Resonator

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 ...
