Researchers Developed Flexible Photonic Devices

Flexible Photonic Devices
Photonics will have a direct impact on many areas of our daily life. Soon photonics will be fundamental, both for the improvement or replacement of existing processes and for the development of new solutions and new products.

On the other hand, society demands products with better and better features: new functionalities and improved properties, lightweight, flexible photonic devices, and capable of adapting to different materials and surfaces. Likewise, these developments must be competitive and not increase the price of the final product.

A team of MIT Associate professor Juejin Hu from the University of Central florida, China and France has developed a new method of making light based photonic devices. These special flexible photonic devices is made from a kind of glass called Chalcogenide. This specialized kind of glass material has a great flexible property which can be bend and strech to the very large extent without any damage. These flexible photonic devices can be used in field of biomedical sensors and flexible connectors in Electronics.

How about a device that can simultaneously detect blood oxygen level, heart rate and blood pressure? Yes, these flexible photonic devices of optical technology which are made from the strechy and bendable material can be mounted in skin to monitor the condition.

By using these kinds of new light based flexible photonic devices, we can stave off the condition for the conversion process. Because, if the original data is light based is having the advantages for a lot of applications.

The current photonic devices applied in the field are made up of rigid materials on rigid matters thus rises an intrinsic counterpart. The polymer based softmaterials is having a less refractive index tracks to not so good ability to circumscribe a light beam. To confront this issue, the team of MIT researchers have developed a stiff material that can stretch and bend which is almost like a Rubber. Its confuguration is like a spring made from a polymer matter has no noticeable abjection in its optical performance.

Other flexible photonic devices that are made by implanting nanorods of a rigid substrates in a polymer base need extra developmental steps. And hence they are not congruous with current systems. These flexible photonic devices can also be used for applications where the devices require to adapt to the rippled surfaces of some other material. But optics technology is extremely sensitive to strain, thus can observe deformations of lower than one hundredth of one percent.

This team recently has formulated a way of segregating layers of photonics, made of chalcogenide and graphene with customary semiconductor photonic electronic equipment. Current method of segregating such material need them to be made on a surface and then take off and tranfern to a semiconductor thin layer. This process is very difficult. But the new procedure permits the layers to be fancied directly on the surface of a semiconductor. This process no need a special temperature condition for the entire process and thus allows very simplified fabrication and more punctilious coalition.

This team of MIT researchers have confirmed very soon they develop this new technology of flexible photonic devices to reach commercially.
