Project description
On-chip demodulator solution for THz communication
The use of the terahertz band in telecommunication technologies has the potential to enormously boost data rates in high-speed wireless communication. Terahertz based communications aim at surpassing 5G systems with unparalleled benefits to future 6G systems, which could operate at a 300-600 GHz range and allow for transmission rates of up to 1 000 gigabits per second. Unfortunately, critical challenges in demodulating high-frequency signals significantly inhibit their potential due to the need for expensive, bulky and limiting electronics. The ERC-funded TopoChipTHz project will develop a revolutionary on-chip topological coherent de-modulator for THz signals, addressing key challenges and providing a solution that is smaller, quieter, more scalable and efficient.
Objective
Recent advancements in terahertz (THz) technology have unlocked the po-tential for ultra-high-speed wireless communication, with data rates far sur-passing those of current 5G systems. Operating in the 300-600 GHz range, future 6G systems could enable wireless transmission rates of up to 1000 gi-gabits-per-second, revolutionizing applications like metropolitan networks and uncompressed video transfer. However, current THz technologies face challenges, especially in demodulating high-frequency signals. Existing la-boratory solutions rely on bulky, expensive electronics with limited band-width, high noise, and non-linearity, hindering the scalability of THz com-munication.
In this project, we propose developing an on-chip topological coherent de-modulator for THz signals using topological photonic crystals, which ex-hibit robust, low-backscattering wave propagation. Leveraging the valley Hall effect in photonic crystals, the device will feature waveguides, beamsplitters, mixers, and balanced detection outputs, integrated on a silicon chip. This all-optical architecture offers a significant improvement over tra-ditional electronics-based systems, with a target demodulation bandwidth over 50 GHz for signals at 300 GHz.
The proposed solution will address key bottlenecks in current THz technolo-gy, including size, bandwidth, and signal-to-noise ratio. As one of the first functional on-chip demodulators for THz frequencies, this device sets a new standard for future applications. Its compact design, scalability, and en-hanced performance position it as a key enabler for 6G wireless systems, driving ultra-fast data transfer for real-world use cases.
