      Fiber laser sensor array 

      Alavie, A. Tino; Karr, Shawn E.; Othonos, Andreas S.; Measures, Raymond M. (Publ by Society of Photo-Optical Instrumentation Engineers, 1993)
      An intracore Bragg grating and a broadband reflector are used as cavity end mirrors of a tunable Erbium-doped fiber laser where the Bragg grating serves the dual purpose of the tuning element and the sensor. This fiber ...

      A Multiplexed Bragg Grating Fiber Laser Sensor System 

      Alavie, A. Tino; Karr, S. E.; Measures, R. M.; Othonos, Andreas S. (1993)
      A technique for multiplexing Bragg gratings in a fiber laser arrangement is described. This technique has successfully been used to multiplex two and three Bragg gratings with very little crosstalk. The Bragg grating laser ...

      Raman spectroscopy using a fiber optic probe with subwavelength aperture 

      Tsai, D. P.; Othonos, Andreas S.; Moskovits, M.; Uttamchandani, D. (1994)
      Raman spectroscopy with subwavelength spatial resolution of a diamond sample was recorded using a tapered fiber optical probe in conjunction with a conventional Raman spectrometer. The experiment demonstrates the potential ...
