In advanced fields such as precision sensing, quantum communication, and high-speed coherent optical communication, light is more than just an energy carrier; it is a precise “tool” carrying complex information. In these applications, the polarization state—the orientation of the electric field’s vibration—becomes a critical parameter that must be strictly controlled and maintained. Uncontrolled, random changes in…

In the realm of optical fiber communications, multimode fiber (MMF) has long been the workhorse for short-distance, high-bandwidth applications within buildings, data centers, and campuses. To standardize performance, the International Organization for Standardization (ISO) and the Telecommunications Industry Association (TIA) have classified MMF into categories denoted as OM1, OM2, OM3, OM4, and OM5. These designations…
