Cheng Hsiang Lin,Cheng Hsiang Lin,Lan Jiang,Y. H. Chai,Hai Xiao,Shean-Jen Chen,Hai-Lung Tsai +6 more
TL;DR: In this paper, a plano-convex cylindrical and spherical microlens arrays were fabricated by modifying the microstructure of Foturan glass using femtosecond (fs) direct writing followed by thermal treatment, wet etching, and additional annealing.
Journal ArticleDOI
Ultra-Abrupt Tapered Fiber Mach-Zehnder Interferometer Sensors
TL;DR: A fiber inline Mach-Zehnder interferometer (MZI) consisting of ultra-abrupt fiber tapers was fabricated through a new fusion-splicing method, capable of in situ detection in many areas of interest such as environmental management, industrial process control, and public health.
Journal ArticleDOI
Femtosecond laser fabrication of long period fiber gratings and applications in refractive index sensing
TL;DR: In this paper, an improved point-by-point inscription method is proposed to fabricate long period fiber gratings (LPFGs) by using a laser operating at 800nm with 35-fs duration pulses.
Journal ArticleDOI
Investigation of transport phenomena and defect formation in pulsed laser keyhole welding of zinc-coated steels
TL;DR: In this paper, a mathematical model and the associated numerical techniques have been developed to study the transport phenomena and defect formation mechanisms in pulsed laser keyhole welding of zinc-coated steels.
Journal ArticleDOI
One-step fabrication of nanostructures by femtosecond laser for surface-enhanced Raman scattering.
TL;DR: An efficient fabrication of nanostructures on silicon substrates for surface-enhanced Raman scattering (SERS) using the femtosecond laser direct writing technique provides an opportunity to incorporate the SERS capability in a functional microchip.
