  • a compact fiber tip Micro Cavity sensor for high pressure measurement
    IEEE Photonics Technology Letters, 2011
    Co-Authors: Long Jin, Wei Jin
    Abstract:

    A novel fiber-tip Micro-Cavity pressure sensor was fabricated by use of a fusion splicer and a pressurizing gas chamber. The fabrication process is simple and efficient without the need for careful cleaving, chemical etching, and bonding. Micro-cavities with wall thickness of a few Micrometers demonstrated a pressure sensitivity of ~ 315 pm/MPa . The sensors have compact size, good mechanic strength, and high temperature stability up to 600°C, and may be potentially used for pressure sensing in a high-temperature environment.

  • A novel fiber-tip Micro-Cavity sensor for high temperature application
    21st International Conference on Optical Fiber Sensors, 2011
    Co-Authors: Wei Jin, Long Jin
    Abstract:

    A low cost fiber-optic Micro-Cavity interferometric sensor is presented. The Micro-Cavity is fabricated at the fiber tip by splicing a silica capillary to a single mode fiber and then heating/melting the capillary to form a Microsphere with an internal air Cavity. The sensor has small size and good mechanical strength, and may be used for pressure and temperature measurement in high temperature environment.

  • Ultrafast nonlinear dynamics of whispering-gallery mode Micro-Cavity lasers.
    Optics express, 2006
    Co-Authors: Andreas Klaedtke, Ortwin Hess
    Abstract:

    We explore the ultrafast spatio-temporal dynamics of whispering-gallery Micro-Cavity lasers. To model the dynamics of the nonlinear whispering-gallery modes we develop a three-dimensional Finite-Difference Time-Domain modelling framework based on the spin and therefore optical polarisation resolved Maxwell-Bloch equations. The numerical algorithm brings together a real value form of the optical Bloch equations with the curl part of Maxwell’s equations. The Hamiltonian of the two-level system contains either linear or circular polarised transitions. In cylindrical Micro-Cavity lasers the coherent, nonlinear emission process leads to ultrafast fan-like rotational phase dynamics of the degenerate whispering-gallery modes. This rotation is shown to be arrested in gear-shaped Micro-Cavity lasers followed by an over-damped relaxation oscillation.
