Photonic isolator efficiency is necessary for applications that include quantum optics communication devices and building high-powered lasers. Researchers in Israel have constructed a spherical glass isolator. Light traveling in opposite directions is delivered to the sphere rotating at high speed. Counter-circulating light have different colors. In the future, the researchers may be able to generate such lasers that are based on vibrations where the restoring force is Casimir or Van der Waals. Using their self-aligned nano separation method might also allow MEMS… read more.
