Transporting of two-photon quantum states of light through a phase-separated
The invention of low-loss optical fiber in 1970 made it possible to efficiently transport information from one place to another over long distances without the loss of information
Conventional optical fibers are the most common way of data transmission nowadays.
The systems are reaching information-carrying capacity limits because of the exponential increase of data generation.
Research now focuses on finding new ways to utilize the full potential of the fibers by examining their inner structure and applying new approaches to signal generation and transmission
Extending the research from classical to quantum light is how applications in quantum technology are enabled
The physicist Philip W. was born in the late 50s. What is now called Anderson Localization was predicted by Anderson, who also made contributions to particle physics and superconductivity
An electron in a disordered system can either move freely through the system as a whole or be tied to a specific position as a "localized electron," according to Anderson's theory
Light waves can also experience Anderson localization, just as the waves of electrons in metal do
Experiments have been performed on optical fibers that demonstrate Anderson localization in classical or conventional light in two dimensions while it's being transmitted through the third dimension
conventional single-mode optical fibers, where data is transmitted through a single core, a phase-separated fiber or phase-separated Anderson fiber is made of many glass strands embedded in a glass matrix
During its fabrication, as borosilicate glass is heated and melted, it is drawn into a fiber, where one of the two phases of different Refractive indexes tends to form strands of glass
Since there are two Refractive indexes in the material, this leads to a phenomenon known as a "lateral disorder", which leads to Anderson's localization of light in the material
An optical fiber that can spread multiple optical beams in a single optical fiber was created by experts in optical fiber fabrication
there are many parallel optical beams that can travel through the fiber with minimal spacing between them, this PSF is very suitable for such experiments.
