Photonics: The Cutting Edge Technology to a Global Communications Network
Scientists are exploring photonics as an alternate to electronic systems to transmit, distribute, and process high volumes of digital information at 'lightening' speed. Other than its communication properties, light's interface with other materials makes it an ideal precision measurement, fine process, and diagnostic tool. Demands for increasingly diminutive devices, urgent need for higher bandwidth in telecommunications, new market participants and increased financial backing drive this technology. Significant breakthroughs enabling commercial viability could make photonics the latest frontier of human knowledge.
This Technical Insights study examines new niche applications developing under Photonic Technologies such as optical communications, photonic networking, optical computing, optical recording, quantum encryption, and ablation.
Photonic Networks Provide High Bandwidth within a Small Footprint
The strive to construct a global communications network has given photonics research fresh impetus. A single optical fiber can carry the equivalent of 300,000 telephone calls at the same time, says the analyst. Photonics' has the potential to improve information systems and image-processing technologies vastly. Speed, immunity to interference, increased bandwidth, parallel information processing abilities and enhanced data-storage capacity are some of the advantages of working with light, compelling investors to pump huge funding into photonic research activities.
Optical communication devices that provide high bandwidth yet small footprints will also drive the optical network of the future. Other than boosting demand for conventional Internet usage due to it's higher broadband penetration abilities, photonics can also offer new bandwidth-rich applications.
Photonics Proves Invaluable in Industrial and Medical Applications
Photonics has tremendous scope since it is multidisciplinary, encompassing areas of science and engineering. Industrial applications for optical fiber technology look promising in specialized areas such as biophotonics, where its usage is invaluable in biotechnology, microbiology, medicine, surgery, and veterinary medicine. Photonics is also emerging as the key solution to clinical and research problems through techniques of advanced spectroscopy, laser, microscopy, and fiber-optic imaging.
However, creating suitable, cost-effective photonic waveguides that channel light with minimal transmission loss is proving to be a challenge for manufacturers. The integrating of photonics and electronics components requires a high degree of precision in light transmission, facilitated by automated alignment techniques and modified component designs, says the analyst. While electronics has become more versatile, portable and miniaturized, photonics equipment is yet to demonstrate its commercial viability.
