OAM Modes

OAM (Orbital Angular Momentum) modes are special patterns of light beams that carry orbital angular momentum, giving them a twisted or helical shape. Think of it like a corkscrew or spiral wave pattern that can be used to encode information. Each mode has a unique twist, allowing multiple signals to share the same space without interfering—much like different lanes on a highway. This property makes OAM modes valuable for increasing data capacity in optical communications, enabling faster and more efficient transmission of information over fiber optics or free-space links.
