Whispering gallery mode resonators (WGMRs) are optical microsensors. Among different types of photonic sensor devices the WGMRs are known with their ultra high quality (Q) factors. One of the important properties of WGMR is the sensitivity to changes in the surrounding medium.
How do whisper chambers work?
This seemingly magical phenomenon can be explained by whispering gallery waves. When whispers hit the circular or semicircular surface of the gallery, those vibrations cling to the surface and “creep” along the gently curving path. The slight angle of the structure keeps sound waves from dispersing out to either side.
