  • Abstract
    A two-photon confocal microscope lithography technique was used to fabricate nano-defect structure in the chiral helicoidal system and higher-order confinement structure based on the chiral liquid crystals. Tunable defect mode and laser actions on this nano-modulated chiral helix structure have been demonstrated.
