| 1 | Femtosecond laser additive and subtractive micro-processing:enabling a high-channeldensity silica interposer for multicore fibre to silicon-photonic packaging显示文摘Great strides have been made over the past decade to establish femtosecond lasers in advanced manufacturing systems for enabling new forms of non-contact processing of transparent materials.Research advances have shown that a myriad of additive and subtractive techniques is now possible for flexible 2D and 3D structuring of such materials with micro-and nano-scale precision.In this paper,these techniques have been refined and scaled up to demonstrate the potential for 3D writing of high-density optical packaging components,specifically addressing the major bottleneck for efficiently connecting optical fibres to silicon photonic(SiP)processors for use in telecom and data centres.An 84-channel fused silica interposer was introduced for high-density edge coupling of multicore fibres(MCFs)to a SiP chip.Femtosecond laser irradiation followed by chemical etching was further harnessed to open alignment sockets,permitting rapid assembly with precise locking of MCF positions for efficient coupling to laser written optical waveguides in the interposer.A 3D waveguide fanout design provided an attractive balancing of low losses,modematching,high channel density,compact footprint,and low crosstalk.The 3D additive and subtractive processes thus demonstrated the potential for higher scale integration and rapid photonic assembly and packaging of micro-optic components for telecom interconnects,with possible broader applications in integrated biophotonic chips or micro-displays. | Gligor Djogo Jianzhao Li Stephen Ho Moez Haque Erden Ertorer Jun Liu Xiaolu Song Jing Suoand Peter R Herman | 2019 | International Journal of Extreme Manufacturing2019，1，4： | 1 |
| 2 | Quantized structuring of transparent films with femtosecond laser interference显示文摘The confinement of laser interactions inside transparent materials assisted by tight optical focusing and short-pulsed nonlinear interactions has driven many high-resolution patterning and probing applications in science and technology.In thin transparent films,laser interactions confined to the film/substrate interface have underpinned blistering and ejection processes for nanofluidic channel fabrication,film patterning and cell catapulting.Here,we harness femtosecond lasers to drive nonlinear interactions within Fabry–Perot interference fringes to define narrow nanolength scale zones for highly resolved internal structuring of a film of refractive index,nfilm,at fringe maxima separated by l/2nfilm.This novel interaction internally cleaves the film to open subwavelength internal cavities and form thin membranes at single or multiple depths from which follow significant opportunities for writing multilevel nanofluidic channels inside the film,as well as ejecting nanodisks at quantized film depths for coloring and three-dimensional surface patterning that promise new compact types of lab-in-film devices. | Kitty Kumar Kenneth KC Lee Jianzhao Li Jun Nogami Nazir P Kherani Peter R Herman | 2014 | Light(Science & Applications)2014，3，1： | 0 |
