TL;DR: In this article, a global-based estimator for surface plasmon resonance tilted fiber Bragg grating (SPR-TFBG) was proposed based on a spectral subtraction approach.

TL;DR: In this article, the long-wavelength-band (L-band) gain-clamped erbium-doped fiber amplifier with a co- and counter-propagating ring laser is investigated.

TL;DR: In this article, a four-wave mixing (FWM) effect in the reduced length of Bi-based erbium-doped fiber (Bi-EDF) with both open and ring configurations was demonstrated.

TL;DR: An optical amplifier is a device which receives some input optical signal and generates an output optical signal with higher power without the conversion to an electrical signal during the intermediate stages as discussed by the authors, where the amplification process takes place in a so-called gain medium, which is either insulators doped with some laseractive ions or semiconductors.

TL;DR: Partial differential equations are used to describe the relation between liquid drop volume and other important parameters of a fluid flow, including maximum wetted region diameter achieved, time taken to reach each spreading process phase, and evaporation rate.
