    • Characterizing ultrashort optical pulses using second-order nonlinear nanoprobes 

      Li, H. F.; Zhang, Z.; Xu, Q. A.; Shi, K. B.; Jia, Y. S.; Zhang, B. G.; Xu, Yong; Liu, Z. W. (AIP Publishing, 2010-12-01)
      We report a second-order nonlinear nanoprobe for characterizing ultrafast optical near fields. The proposed nanoprobe comprises second harmonic nanocrystals attached to a carbon nanotube, which is in turn attached to a ...
    • High quality factor silica microspheres functionalized with self-assembled nanomaterials 

      Kandas, Ishac L. N.; Zhang, B. G.; Daengngam, C.; Ashry, I.; Jao, Chih-Yu; Peng, B.; Ozdemir, S. K.; Robinson, Hans D.; Heflin, James R.; Yang, L.; Xu, Yong (Optical Society of America, 2013-09-01)
      With extremely low material absorption and exceptional surface smoothness, silica-based optical resonators can achieve extremely high cavity quality (Q) factors. However, the intrinsic material limitations of silica (e. ...
