a compact fiber tip Micro Cavity sensor for high pressure measurement
IEEE Photonics Technology Letters, 2011Co-Authors: Long Jin, Wei JinAbstract: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, 2011Co-Authors: Wei Jin, Long JinAbstract: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, 2006Co-Authors: Andreas Klaedtke, Ortwin HessAbstract: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.
