High-performance terahertz modulators induced by substrate field in Te-based all-2D heterojunctions

This article presents a study on high-performance terahertz (THz) modulators using Te-based 2D heterojunctions, a promising development for next-generation communication technologies. These modulators, created by a team led by Professor Qingli Zhou and others, overcome the usual trade-off between modulation depth and speed, achieving high modulation depth on a picosecond timescale. By leveraging the unique properties of 2D materials and substrate engineering, they demonstrated significant improvements in device performance, including ultra-high modulation depth, short carrier lifetimes, low loss, and broad bandwidth. This research could guide future designs of efficient, high-speed THz photonic devices. For further details, you can read the full article here:
