Measurement of sugar percentage or ºBrix (1 ºBrix=1% sugar mass percent) is crucial in many applications, such as fruit juice, wine making, carbonated beverage industry

Periodic perturbations of the optical fiber core refractive index along the fiber length can be obtained using different techniques, such as the exposure to an intense laser irradiation,

SLED Broadband light sources can take advantage from broadband emission and high power as it is described in our previous post about SLEDs. These characteristics are

The continuous emerging of novel manufacturing techniques, either top-down or bottom-up [1], enables a more and more precise control of the growth of structures at

In this post we will briefly go through a theoretical introduction of evanescent field associated to optical fiber sensors and its applications to perform absorption

In one of our last articles (see article) we explained the basic principles of superluminescent diodes (SLD) operation. After understanding what means that the SLDs have a high spatial coherence

In this article we are going to introduce the concept of coherence, as it plays a major role when selecting a light source for a

The risks associated to water contamination are very important for human health and environmental protection. Therefore, water quality monitoring is a major concern of current

Superluminescent diode (SLD/SLED) lighting principles unveiled Nowadays, lasers and LEDs are part of the everyday life thanks to the Star Wars lightsabers or the low

Insertion loss and return loss or power signal transmitted along a fiber optic link, are generally expressed in dB (decibels) and should always be a
