• Enhanced Nanoparticle Detection with Liquid Droplet Resonators 

      Foreman, M.R.; Avino, Saverio; Zullo, Rosa; Loock, Hans-Peter; Vollmer, F.; Gagliardi, G. (2016-02-25)
      Whispering gallery mode particle sensing experiments are commonly performed with solid resonators, whereby the sensing volume is limited to the weak evanescent tail of the mode near the resonator surface. In this work we ...
    • Loss Determination in Microsphere Resonators by Phase-Shift Cavity Ring-Down Measurements 

      Barnes, Jack A.; Carver, B.; Fraser, James M.; Gagliardi, G.; Loock, Hans-Peter; Tian, Zhaobing; Wilson, M.W.B.; Yam, Scott S.-H.; Yastrubshak, O. (2016-03-21)
      The optical loss of whispering gallery modes of resonantly excited microresonator spheres is determined by optical lifetime measurements. The phase-shift cavity ring-down technique is used to extract ring-down times and ...
    • Optical Fiber Sensing Based on Reflection Laser Spectroscopy 

      Gagliardi, G.; Salza, M.; Ferraro, P.; Chehura, E.; Tatam, R.P.; Gangopadhyay, T.K.; Ballard, Nicholas; Paz-Soldan, Daniel; Barnes, Jack A.; Loock, Hans-Peter; Lam, T.T.; Chow, J.H.; De Natale, Paolo (2016-03-22)
      An overview on high-resolution and fast interrogation of optical-fiber sensors relying on laser reflection spectroscopy is given. Fiber Bragg-gratings (FBGs) and FBG resonators built in fibers of different types are used ...
