How Does HOT: Optomechanical optical circulator Work?

HOT is like a smart traffic cop that guides light through a road made of tiny mirrors and moving parts.

Imagine you're playing with toy cars on a track. You have three lanes: one for red cars, one for blue cars, and one for green cars. The traffic cop lets the red cars go from lane 1 to lane 2, blue cars from lane 2 to lane 3, and green cars from lane 3 back to lane 1, all without getting confused or crashing.

In HOT, instead of toy cars, we have light. Instead of a traffic cop, we have a special device that uses moving mirrors and tiny mechanical parts, like a spinning wheel inside a box. When light comes in from one side, the moving mirror sends it to another side, just like your traffic cop guiding the cars.

This works because when something moves fast enough (like a tiny mirror), it can change where the light goes. This makes HOT really good at sending signals through fiber-optic cables or even controlling lasers, like how a toy car track helps you send different colored cars to different places, but with light instead of cars!
