Micro-channels machined in microstructured optical fibers by femtosecond laser.

چکیده
Micro-channels were fabricated in hollow-core photonic bandgap fiber (HC-PBGF) and suspended-core holey fiber (SC-HF) by femtosecond Ti:sapphire laser irradiation. Gaseous access was demonstrated via these engineered ports to the core of HC-PBGF and the hollow cladding of SC-HF. Femtosecond laser micro-machining caused no additional transmission loss in HC-PBGFs. This allowed a novel gas cell to be produced, in which gaseous access was provided solely through two micro-channels. Acetylene diffusion was also confirmed through a micro-channel leading to a single cladding airhole in SC-HF. This further highlighted the fabrication technique's precision, selectivity, and potential for developing fiber-based micro-fluidic devices.

Femtosecond laser-assisted selective infiltration of microstructured optical fibers.
A new method of selectively infiltrating microstructured optical fibers with the assistance of femtosecond laser micromachining is presented. With this technique, any type of air-holes in the cross-section of the microstructured optical fibers can be selectively infiltrated with liquids, which opens up a highly efficient, precise, flexible and reliable way of selective infiltrating and has high...
متن کاملFabrication, splicing, Bragg grating writing, and polyelectrolyte functionalization of exposed-core microstructured optical fibers.
Femtosecond laser written Bragg gratings have been written in exposed-core microstructured optical fibers with core diameters ranging from 2.7 µm to 12.5 µm and can be spliced to conventional single mode fiber. Writing a Bragg grating on an open core fiber allows for real-time refractive index based sensing, with a view to multiplexed biosensing. Smaller core fibers are shown both experimentall...
متن کاملUltrafast femtosecond-laser-induced fiber Bragg gratings in air-hole microstructured fibers for high-temperature pressure sensing.
We present fiber Bragg grating pressure sensors in air-hole microstructured fibers for high-temperature operation above 800 degrees C. An ultrafast laser was used to inscribe Type II grating in two-hole optical fibers. The fiber Bragg grating resonance wavelength shift and peak splits were studied as a function of external hydrostatic pressure from 15 psi to 2000 psi. The grating pressure senso...
متن کاملEnhanced machining of steel using femtosecond pulse pairs
In this study we report on the ablation of steel using femtosecond double-pulse trains. Double-pulse trains with pulse-to-pulse separations between 1 ps and 1 ns were used to machine micro-channels in a steel sample. The depths of the laser-ablated channels were measured to characterize the efficiency of the ablation process. Results show that using a double-pulse train with an optimal separati...
