Researchers Attain Milestone for Ultra-fast Communications


In yet another move for the furtherance of computing and communication technology, research conducted at the University of Utah has culminated into a milestone achievement. A special kind of perovskite has been discovered, which is a combination of an inorganic and organic compound and is structurally similar to the original mineral. The distinct feature is that this substance can be arranged in layers on a silicon wafer so as to create an important component for the next-generation communication systems.

The next-generation communication systems that uses bandwidth from the terahertz spectrum would use light instead of electricity to transmit data. This would allow cellphone and internet users to transmit information thousand times faster than what is possible today.

Use of Light Frequency to Upturn Speed of Cellular Devices to Transmit Information 

Positioned in between infrared light and radio waves, the terahertz range is a band that utilizes frequency between 100 gigahertz to 10,000 gigahertz. Research is underway to use these light frequencies for the transfer of information. Using frequency in the terahertz range can dramatically boost the speed of devices such as cell phones or internet modems.

Moreover, the researchers learned an important component of that puzzle: by placing a special kind of perovskite on a silicon wafer, the terahertz waves passing by can be modulated using a simple halogen lamp. The modulation of amplitude of terahertz radiation is important for the transfer of data in this type of communication system.

Previously, efforts for modulating the amplitude of terahertz waves involved the use of an costly, high-power laser. This setup is different as the lamp not only allows modulation but also modulation of specific color of light.
