Single-mode sapphire fiber Bragg grating

, 2021
We present here the inscription of single-mode waveguides with Bragg gratings in sapphire. The waveguide Bragg gratings have a novel multi-layer depressed cladding design in the 1550 nm telecommunications waveband.

Statistical Model for Polarization Mode Dispersion in Single Mode Fibers

مجلة بغداد للعلوم, 2010
As the bit rate of fiber optic transmission systems is increased to more than , the system will suffer from an important random phenomena, which is called polarization mode dispersion. This phenomenon contributes effectively to: increasing pulse width,

High-fidelity delivery of kilowatt-level single-mode lasers through a tapered multimode fiber over one hundred meters

High Power Laser Science and Engineering
The immediate priorities for high-power delivery employing solid-core fibers are balancing the nonlinear effect and beam deterioration. Here, the scheme of tapered multimode fiber is experimentally realized. The tapered multimode fiber, featuring a 15 m (

Steel Beam Compressive Strain Sensor Using Single-Mode-Multimode-Single-Mode Fiber Structure

IEEE Photonics Journal, 2016
A steel beam compressive strain sensor using single-mode-multimode-single-mode (SMS) fiber structure is demonstrated. Parallel measurements are made using an electrical resistance (ER) strain gauge along with the SMS to sense the compressive strain on ...

Anti-Resonant Fiber with Large Mode Area and Ultra-High HOMER for Near-Infrared High-Power Laser

Photonics
A novel anti-resonant hollow-core fiber (AR-HCF) is proposed. The fiber uses cross-nested circular cladding tubes including single-nested and non-nested tubes in the near-infrared spectral region of 1.3–1.7 μm.
