1.5 µm Emission Properties of Erbium‐Implanted Thin‐Film Lithium Niobate

Advanced Optical Materials, Volume 14, Issue 34, 11 September 2026.
Optically active Er3+ ions are incorporated into x‐cut lithium niobate on insulator utilising a focused ion‐beam implantation method capable of sub‐100 nm precision. The implanted regions exhibit telecom‐band emission, with a reduction in photoluminescence intensity and lifetime below 50 K, consistent with pyroelectric‐field effects in the host ...

Nanomaterial‐Incorporated Nonlinear Optical Waveguides Explored With All‐Fiber Multiphoton Polymerization

Advanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Nonlinear waveguides are fabricated via an all‐fiber‐based multiphoton polymerization approach incorporating upconversion nanoparticles (UCNPs), which enable both multiphoton absorption at telecommunication wavelengths and nonlinear saturable absorption operation.

High-power cladding-pumped Raman and erbium-ytterbium doped fibre sources

, 2007
Raman fibres and rare-earth doped silica fibres have been investigated for many years as gain media for the amplification of optical signals in telecommunications thanks to their broad gain bandwidth. They are now widely used for that application.

A New Erbium Doped Fiber Amplifier

Journal of Applied Sciences, 2009
In this study, a new configuration of an Erbium Doped Fiber Amplifier (EDFA’s) is proposed. Double-pass amplification in a dual-stage using a fiber loop-back is incorporated with a Tunable band pass filter. Spontaneous emission is filtered-out in the mid-section to ensure efficient amplification of the signal as it propagates along the fiber. High gain

High‐Power Continuous‐Wave Optical Waveguiding in a Semiconductor Nanowire

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
An in‐line fiber–nanowire–fiber configuration provides efficient coupling of 1550 nm continuous‐wave light into and out of a single CdS nanowire. The output power increases linearly with input power, reaching 1.8 W and corresponding to a guided power of 2.5 W, demonstrating watt‐level continuous‐wave optical waveguiding in a subwavelength semiconductor

Stiffness‐Activated Stellate Cells Drive Pancreatic Cancer Liver Colonization via GMFG‐TNS4 Signaling

Advanced Science, Volume 13, Issue 51, 14 September 2026.
Fibrotic liver stiffness activates hepatic stellate cells through Piezo1‐dependent calcium influx and ER stress, promoting EV‐associated GMFG release. Delivered GMFG engages TNS4 in pancreatic cancer cells, triggering FAK/AKT signaling, adhesion, and fatty acid synthesis.

Gain-managed nonlinear amplification in an erbium-doped fiber

Optics Express
To our knowledge, we report the first experimental demonstration of gain-managed nonlinear (GMN) amplification of femtosecond pulses in an erbium-doped fiber amplifier (EDFA). We investigated the GMN amplification using two different seed sources, operating at wavelengths of 1530 and 1560 nm.
