Fiber-Optic Bragg Grating Sensor for Photothermally Examinating Moisture of Meat

Photonic Sensors
The illegal water injection into meat not only breaks the market equity, but also deteriorates the meat quality and produces harmful substances. In this work, we proposed a fiber Bragg grating (FBG) sensor that enabled fast, quantitative, and in-situ ...

Effect of an atom on a quantum guided field in a weakly driven fiber-Bragg-grating cavity

, 2010
We study the interaction of an atom with a quantum guided field in a weakly driven fiber-Bragg-grating (FBG) cavity. We present an effective Hamiltonian and derive the density-matrix equations for the combined atom-cavity system.
