Nanomechanical optical fiber with embedded electrodes actuated by joule heating

open access: yes, 2014
Nanomechanical optical fibers with metal electrodes embedded in the jacket were fabricated by a multi-material co-draw technique. At the center of the fibers, two glass cores suspended by thin membranes and surrounded by air form a directional coupler ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

open access: yesAdvanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Fabrication and formation mechanism of poly (L-lactic acid) ultrafine multi-porous hollow fiber by electrospinning

open access: yeseXPRESS Polymer Letters, 2013
Poly(L-lactic acid) (PLLA) ultrafine multi-porous hollow fibers are fabricated by electrospinning with methylene dichloride as solvent. The Kirkendall effect has been widely applied for the fabrication of hollow structure in metals and inorganic ...

Fiber design for high-power low-cost Yb:Al-doped fiber laser operating at 980nm [PDF]

open access: yes, 2007
We investigated an Yb:Al-doped depressed-clad hollow optical fiber (DCHOF) for cladding-pumped 980nm laser operation. With a careful design, the nonzero fundamental-mode cutoff characteristics of a DCHOF allows the competing 1030-1060nm emission to be ...

Opportunity and Challenge for Hollow Core Anti Resonant Optical Fiber in the Long-distance Telecommunication

open access: yesGuangtongxin yanjiu, 2023
The scientific research of Hollow Core Anti Resonant Optical Fiber (HCARF) has made a great breakthrough progress, which is expected to break through some inherent limitations of traditional optical fibers. The HCARF guides the light beam in the air core,

First demonstration of a low loss 37-cell hollow core photonic bandgap fiber and its use for data transmission

open access: yes
A low loss (4.5dB/km) 37-cell core HC-PBGF is reported for the first time. Detailed modal analysis using time of flight and S2 techniques, and error-free 40Gbit/s single mode data transmission are ...

Layered Spin‐Crossover Metal‐Organic Frameworks for Light‐Induced Control of Two‐Dimensional Quantum Materials

open access: yesAdvanced Materials, EarlyView.
Spin‐crossover metal‐organic frameworks (SCO‐MOFs) provide a route to control the electronic and magnetic properties of two‐dimensional quantum materials. By integrating a layered SCO‐MOFs with graphene, CrSBr, and NbSe2 nanodevices, thermally and light induced spin transitions induce strain that reversibly modulates charge transport, magnetic memory ...
