Planar lightwave circuits

Planar lightwave circuits (PLCs) are advanced optical devices that guide and manipulate light on flat surfaces, much like electronic circuits manage electrical signals. They are made from materials that can transmit light, allowing for functions such as splitting, combining, and redirecting light beams. Used in telecommunications, sensors, and data processing, PLCs enable faster and more efficient communication by harnessing the power of light, which travels faster than electricity. Their compact design allows for integration into various technologies, leading to advancements in high-speed internet and other optical applications.
