Researchers have developed centimeter scale films using aligned chiral carbon nanotubes to achieve strong second harmonic generation. This breakthrough allows for more efficient light conversion in silicon photonics and telecommunication systems by utilizing the intrinsic chirality of the nanotubes. These thin films can be integrated into nanophotonic circuits and quantum optical devices. The scalable vacuum filtration method used in the study provides a potential path for CMOS compatible manufacturing of low power optical components.
