Photonics is the branch of science and technology that deals with the study and manipulation of light. It involves the use of photons, the smallest unit of light, to create, transmit, and detect information.
Supermodes refer to the multiple modes or paths that light can travel through in a photonic system. These modes can be controlled and manipulated to optimize the performance of a photonic device.
PBGFs, or photonic bandgap fibers, are a type of optical fiber that uses a periodic structure to confine and guide light. They are used in applications such as telecommunications, sensing, and laser delivery.
Coupling in fibre optics refers to the transfer of light between two or more optical fibers. This can be achieved through physical contact, such as splicing or fusion, or through non-contact methods, such as evanescent field coupling.
Photonics offers several advantages in communication systems, including high bandwidth, low loss, and immunity to electromagnetic interference. It also allows for the transmission of large amounts of data over long distances, making it ideal for long-distance communication.
