TL;DR: In this paper, an optical fiber sensor capable of simultaneously measuring strain, temperature and refractive index is presented. But the sensor is based on the combination of two fiber Bragg gratings written in a standard single-mode fiber, one in an untapered region and another in a tapered region, spliced to a no-core fiber.

TL;DR: In this paper, the authors report the first extended study of the inscription of Bragg gratings in surface-core fibers and their application in refractive index and directional curvature sensing.

TL;DR: In this article, a hybrid cladding composed of a Kagome-tubular lattice (HKT) was proposed to reduce the confinement loss and preserve robust single-mode operation.

TL;DR: The development of a side-hole photonic-crystal fiber (SH-PCF) pressure sensor for dual environment monitoring is reported and properties (phase and group birefringence, sensitivity to pressure variations) are measured and compared to simulated data.

TL;DR: The design proposed herein opens a new route for the development of HCPCFs that combine robust ultra-low-loss transmission and single-mode beam delivery and provides new insight into IC guidance.
