Sensors, 2013 A stripped no-core optical fiber with a 125 µm diameter was transformed into a symmetric and unbroken optical fiber that tapers slightly to a 45-µm-diameter waist. The laser light can be easily launched into the no-core optical fiber.

Low-loss, high-bandwidth fiber-to-chip coupling using capped adiabatic tapered fibers
APL Photonics, 2020 We demonstrate adiabatically tapered fibers terminating in sub-micron tips that are clad with a higher-index material for coupling to an on-chip waveguide. This cladding enables coupling to a high-index waveguide without losing light to the buried oxide.

Fabrication and sensing characterization of an S-tapered fiber probe
AIP Advances, 2020 This paper presents and analyzes S-tapered fiber probe structures. Cutting a conventional S-tapered fiber and coating its ends with gold film forms a highly reliable reflective layer.

Tapered Multicore Fiber for Lensless Endoscopes
ACS Photonics, 2022 We present a novel fiber-optic component, a "tapered multi-core fiber (MCF)", designed for integration into ultra-miniaturized endoscopes for minimally invasive two-photon point-scanning imaging and to address the power delivery issue that has faced MCF based lensless endoscopes.

Brillouin lasing in single-mode tapered optical fiber with inscribed fiber Bragg grating array
Results in Physics, 2018 A tapered optical fiber has been manufactured with an array of fiber Bragg gratings (FBG) inscribed during the drawing process. The total fiber peak reflectivity is 5% and the reflection bandwidth is ∼3.5 nm. A coherent frequency domain reflectometry has

Mode evolution in long tapered fibers with high tapering ratio
Optics Express, 2012 We have experimentally studied fundamental mode propagation in few meters long, adiabatically tapered step-index fibers with high numerical aperture, core diameter up to 117 μm (V = 38) and tapering ratio up to 18. The single fundamental mode propagation was confirmed by several techniques that reveal no signature of higher-order mode excitation.

Tapered Polymer Fiber Inclinometers
IEEE Photonics Journal, 2020 This work proposes a novel, highly sensitive, and simple structure based on a tapered polymer as a tilt fiber sensor to sensitively measure tilt angles (θ).The fiber-optic tilt sensor consists of a tapered polymer and single-mode fibers (SMF), into

The New Tapered Fiber Connector and the Test of Its Error Rate and Coupling Characteristics
International Journal of Optics, 2017 Since the fiber core is very small, the communication fiber connector requires high precision. In this paper, the effect of lateral deviation on coupling efficiency of fiber connector is analyzed.
