Novel concept of multi-channel fiber optic surface plasmon resonance sensor [PDF]

, 2009
A novel multi-channel fiber optic surface plasmon resonance (SPR) sensor is reported. The sensing structure consists of a single-mode optical fiber, covered with a thin gold layer, which supports a surface plasmon (SP), and a Bragg grating.

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection

Advanced Science, EarlyView.
Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Optical Fiber Bragg Grating Temperature Sensor

Diyala Journal of Engineering Sciences, 2014
In this work, uniform Fiber Bragg Grating (FBG) temperature sensor system were implemented and investigated due to measurement of the Bragg wavelength shift. An (FBG) is an optical fiber in which the refractive index in the core is perturbed by Germanium, forming a periodic index modulation profile.
