    Terahertz Vortex Laser Puts Beam Generation and Shaping on One Chip

    A new semiconductor platform has brought the prospect of compact, structured terahertz systems materially closer by generating, guiding, and shaping a terahertz vortex beam on a single chip. In work highlighted by the American Institute of Physics, Chuanfeng Yan and colleagues demonstrated an...
