  • Topological defects in nematic liquid crystals can be controlled upon external stimuli for designing novel photonic materials. Here, Hashemiet al. show geometry-induced formation of fractal defects in nematic fluids with the fractal self-similarity more than 90% from micrometers to nanometres.

  • For terahertz optoelectronics to find broader applications, more efficient sources and detectors are needed. Towards this end, Berry et al. demonstrate the use of plasmonic contact electrodes for both terahertz emitters and detectors, finding large enhancement over standard photoconductive devices.
