TL;DR: In this paper, the authors review recent advances in meta-structured waveguides that synergize various functional subwavelength photonic architectures with diverse waveguide platforms, such as dielectric or plasmonic waveguide and optical fibers.

TL;DR: Through both theoretical research and experiment, the bidirectional pumping configuration presented in this paper proves to be able to convert 976 nm pump laser to 1070 nm laser via Yb3+ transfer, which is then converted into 1123 nm Raman laser via the first-order Raman effect without the appearance of any higher-orderRaman laser.

TL;DR: In this paper, the authors proposed a universal design strategy for versatile on-chip mode-selective coupling with polarization sensitivity, multiple working wavelengths, and high efficiency concurrently, combining the Jones matrix model with generalized Snell's law under the phase-matching condition.

TL;DR: A monolithic fiber-Bragg-grating-based (FBG-based) master oscillator power amplification configuration fiber laser with a narrow linewidth at high-power level is demonstrated.

TL;DR: A side-pumping all-fiber coupler with the coupling efficiency of 90.1% and the coupling power of 144.7 W was reported in this paper, which is beneficial to investigate efficient and reliable high power fiber lasers and amplifiers.
