    • Broadband Transparent Optical Phase Change Materials 

      Li, Junying; Yadav, Anupama; Lin, Hongtao; Du, Qingyang; Michon, Jerome; e.a. (Optical Society of America, 2017-05)
      We report a new group of optical phase change materials Ge-Sb-Se-Te (GSST) with low loss from telecom bands to LWIR. We further demonstrated GSST-integrated SiN photonics with significantly improved switching performance ...
    • Chalcogenide glass-on-graphene photonics 

      Lin, Hongtao; Song, Yi; Huang, Yizhong; Kita, Derek M.; Wang, Kaiqi; e.a. (Springer Nature, 2017-10)
      Two-dimensional (2D) materials are of tremendous interest to integrated photonics, given their singular optical characteristics spanning light emission, modulation, saturable absorption and nonlinear optics. To harness ...
    • Integrated photonics for infrared spectroscopic sensing 

      Yadav, Anupama; Richardson, Kathleen; Lin, Hongtao; Kita, Derek M.; Han, Zhaohong; e.a. (SPIE, 2017-05)
      Infrared (IR) spectroscopy is widely recognized as a gold standard technique for chemical analysis. Traditional IR spectroscopy relies on fragile bench-Top instruments located in dedicated laboratory settings, and is thus ...
    • (Invited) Mechanically Flexible Integrated Photonic Systems for Sensing and Communications 

      Yadav, Anupama; Richardson, Kathleen A; Li, Lan; Lin, Hongtao; Michon, Jerome; e.a. (Electrochemical Society, 2017-04)
      Conventional integrated photonic devices are fabricated on rigid semiconductor or dielectric substrates and are therefore inherently incompatible with soft biological tissues. Over the past few years, we have developed a ...
    • A new twist on glass: A brittle material enabling flexible integrated photonics 

      Li, Lan; Lin, Hongtao; Michon, Jerome; Huang, Yizhong; Li, Junying; e.a. (Wiley Blackwell, 2017-03)
      Glass is in general brittle and therefore usually cannot sustain large deformation. Recent advances in glass material development as well as micro-mechanical designs, however, are set to defy the conventional wisdom through ...
    • On-chip infrared sensors: redefining the benefits of scaling 

      Agarwal, Anu; Yadav, Anupama; Richardson, Kathleen; Luzinov, Igor; Kita, Derek M.; e.a. (SPIE, 2017-05)
      Infrared (IR) spectroscopy is widely recognized as a gold standard technique for chemical and biological analysis. Traditional IR spectroscopy relies on fragile bench-top instruments located in dedicated laboratory settings, ...
    • Understanding aging in chalcogenide glass thin films using precision resonant cavity refractometry 

      Geiger, Sarah J.; Du, Qingyang; Huang, Bin; Shalaginov, Mikhail; Michon, Jerome; e.a. (Optical Society of America (OSA), 2019-04)
      Chalcogenide glass (ChG) thin films have a wide range of applications in planar photonics that rely on the stability of their optical properties. However, most methods do not provide quantitative optical property data at ...
