Harnessing the Power of Optical Vortices for Revolutionary Applications

The concept of optical vortices has been around for decades, but researchers at Harvard University have made significant breakthroughs in understanding and manipulating these corkscrew-like patterns of light. In this article, we'll delve into the world of structured light and explore its potential applications, from advanced materials to cutting-edge technologies.

What are Optical Vortices?

Optical vortices are created when light is guided through a medium, such as a fiber or a waveguide, in a way that creates a rotating pattern. This rotation can be thought of as a topological feature of the light beam, much like a whirlpool in water. Optical vortices have several key properties that make them unique:

• Topological charges: The number of times the light rotates around an axis.
• Spin angular momentum: The intrinsic property of the light that determines its rotation direction.
• Diffraction patterns: The way the light interacts with surrounding objects or media.
