High-Power Passive Fiber Components for All-Fiber Lasers and Amplifiers Application—Design and Fabrication

open access: yesPhotonics, 2018
The most important components for application in high-power all-fiber lasers and amplifiers are, most of all, power combiners, but also mode field adaptors.

Effect of Tapered Interference Fit between Impeller and Shaft in Turbo Machines

open access: yesJournal of Mechanical Engineering, 2018
In Turbo machines, there are many components which are provided with interference to transmit torque and to maintain contact between them. There are transient scenarios where impeller and shaft lose interference and limits the speed of the impeller.

Compact Broadband Low-Loss Taper for Coupling to a Silicon Nitride Photonic Wire

open access: yes, 2017
We demonstrate an ultra-compact waveguide taper in Silicon Nitride platform. The proposed taper provides a coupling-efficiency of 95% at a length of 19.5 um in comparison to the standard linear taper of length 50 um that connects a 10 um wide waveguide ...

Meta-critical thinking, paradox, and probabilities

open access: yesFrontiers in Education
There is as much lack of clarity concerning what “critical thinking” involves, even among those charged with teaching it, as there is consensus that we need more emphasis on it in both academia and society.

Spatial beam self-cleaning and supercontinuum generation with Yb-doped multimode graded-index fiber taper based on accelerating self-imaging and dissipative landscape [PDF]

open access: yes, 2019
We experimentally demonstrate spatial beam self-cleaning and supercontinuum generation in a tapered Ytterbium-doped multimode optical fiber with parabolic core refractive index profile when 1064 nm pulsed beams propagate from wider (122 µm) into smaller (

Spectroscopy, Manipulation and Trapping of Neutral Atoms, Molecules, and Other Particles Using Optical Nanofibers: A Review

open access: yesSensors, 2013
The use of tapered optical fibers, i.e., optical nanofibers, for spectroscopy and the detection of small numbers of particles, such as neutral atoms or molecules, has been gaining interest in recent years. In this review, we briefly introduce the optical
