Nature Photonics: Terahertz Receiver for 6G Wireless Communications

September 2020: Researchers from IPQ/IMT have developed a novel concept for low-cost terahertz receivers that consist of a single diode in combination with a dedicated signal processing technique. In a proof-of-concept experiment, the team demonstrated transmission at a data rate of 115 Gbit/s and a carrier frequency of 0.3 THz over a distance of 110 meters. This demonstration is a first step towards future wireless networks of the 6th generation (6G) that will consist of a multitude of small radio cells that need to be connected by broadband communication links. In this context, wireless transmission at THz frequencies represents a particularly attractive and flexible solution. The results are reported in Nature Photonics (DOI: 10.1038/s41566-020-0675-0).

Publication in Light: Science & Applications: 3D nano-lithography greatly simplifies photonic multi-chip assembly

May 2020: IPQ researchers have demonstrated chiplet-based optical communication engines that exploit 3D-printed freeform waveguides as chip-chip connections. These so-called photonic wire bonds are fabricated in-situ onto the chips by advanced 3D lithography and can efficiently connect a wide variety of waveguide types on different integration platforms. By greatly simplifying the assembly of advanced photonic multi-chip modules, the technique has the potential to transform a variety of applications, ranging from high-speed communications and ultra-fast signal processing to optical sensing and quantum information processing.
