We propose an enhanced multiple-pass group delay (GD) measurement scheme of fiber-
Bragg grating (FBG) based on optical low-coherence reflectometry (OLCR). The fiber loop …

An optical low-coherent interferometric technology for fiber Bragg grating (FBG) sensor array

As optical communication systems begin to fill the available bandwidth in an optical fiber by
transmitting either 40 Gb/s on 200 GHz channel spacings or 10 Gb/s on 50 GHz channel …

With the aim of probing the photonic band structure of waveguiding micro-and nanooptical
devices, we re-introduce the modal local complex reflectivity (LCR) and review the impact of …

We present a low-coherent interferometric system of multiplexed sensors based on pairs of
long-period gratings (LPGs). The LPGs in each pair have approximately 3-dB transitivity and …

The optical low-coherence reflectometer (OLCR) is a very powerful tool to characterize
optical fibres and integrated optical components. However, this is a very complex set-up and …

The optical low-coherent interferometric technology for long-period grating (LPG) Mach-
Zehnder interferometers is described. By including the coupling and recoupling behaviors of …

A dispersion characteristic of a tapered fiber is investigated using temporal interferometer by
