The demand for fast data sharing and processing has sparked a race for greater bandwidth in wireless communication systems. This is described by Edholm's Law, which states that bandwidth and data rates roughly double every year and a half. As our wireless networks near their limits, the quest for even faster data rates prompts researchers to explore uncharted territory: higher frequency bands like millimeter wave, terahertz and optical frequencies.
While millimeter wavelength has been adopted in short-range wireless systems, more is needed for future demands. Optical wireless communication offers high bandwidth but faces challenges due to safety regulations and noise issues. Terahertz communication could provide incredibly fast data rates for everyday applications, even chip-scale ones like integrated microprocessors.
To address this challenge, an exciting solution emerges: using wireless communication methods that operate within the terahertz range. These methods can establish rapid and efficient wireless connections among the various components of the system. However, effectively implementing these technologies requires integrating different components for processing signals within the receiver end of the system.
Our research team has unveiled a comprehensive theoretical framework: a quantum-scale terahertz signal detector and demodulator. This innovative approach taps into the quantum behavior of charge carriers when exposed to intense periodic driving.
