For some areas especially rural areas, deployment of fiber can be expensive and makes it very expensive as well for every household. In the US the government's support for expanding access to broadband internet causes a spike in the demand for fiber products.
Fiber optical tweezers are just one fiber product that uses light to immobilize microscopic particles as small as a single atom in 3D space. Its basic principle is the momentum transfer between light and the object being held. On the other hand, to make the light bend is because of analogous to the water pushing on a damn that blocks the stream pushed by the light onto the object. The optical force is the sign to points to a certain point in space where the particles will be held in the optical trapping technique has won two Nobel prizes in 1997 and 2018. in 1997 it held and cooled down single atoms while in 2018 it offered biologists a tool to study single biomolecules such as DNA and proteins.
The purpose of this idea is to start a perfectly annular symmetric light mode that can only be transmitted in the optical fiber and does not leak into its surrounding space through the fiber tip and have a particle to break the mode symmetry and thereby scatter light into space. Through this, researchers were able to predict potential applications of Invivo single bio particle manipulating experiments with the use of fiber optical tweezers as endless scope to living animals' interior.
Another news related to fiber is that fiber optic cables as we all know are used in internet infrastructure and they can be used for eavesdropping. It's a device that can pick up tiny changes in signals sent through the cable and detect words spoken from over distance away. Optical fibers use a beam of light to transport data across the world, in the ocean and underground, and can be used as sensors detecting earthquakes and tracking whales. Sound travels five times faster in the ocean than in the air making it an effective way for us to assess where sound or high vocals are or going through acoustic monitoring. Acoustic whale monitoring methods involve the deployment of an array of hydrophones to detect sound waves in a certain area and using fiber optics can lead to more sensors over longer distances for better whale monitoring in real-time.
The use of fiber for different purposes gave birth to various possibilities through thorough research that can improve the way we see things on land, air, and water. The latest technology of 5G uses fiber so data transmission could be faster than ever, and we get to enjoy a huge improvement in our society from safety to health monitoring and real-time transfer of information.
