It is challenging to calculate the macro-bending loss of optical fiber when the bending radius
is reduced to sub-millimeter levels, based on Marcuse's theory and its derivative theories …

Inexpensive, lightweight, sensitive, compact, easy-to-install, and mass-producible vibration
sensors are the future wave. This paper validates the use of a 3D-printed doublet bracket …

A few-mode optical fiber surface plasmon resonance sensor with graphene layer is
investigated, firstly, with the aim of studying the behavior of the guided modes and, secondly …

Optical fiber is one of the most used guided transmission media due to its many advantages,
including a high level of data security, a longer lifespan than other communication …

Fiber-to-the-home (FTTH) technology provides the ability to transmit telecommunication data
at a maximum level. In order to achieve this technology, fibers with the lowest bending and …

Although the measurement of liquids temperature is commonly used by Fiber Bragg Grating
(FBG) sensor but its thermodynamic performance has interesting phenomena. This paper …
