In the 1990’s Fiberguide developed 2-dimensional arrays of single mode fibers to meet extraordinarily demanding specifications of Lucent Technologies’ Bell Laboratories. They needed the centerlines of 361 fibers in a 19 x 19 array to be positioned to an absolute accuracy of ± 2.0 microns over the entire array. This required a positioning accuracy beyond that possible with conventional machining methods.
The solution developed and patented by the technical staff at Fiberguide is to use an alignment pate with holes in it to guide the fibers into position. The plate is made from a wafer of silicon and the position of each hole is established by the same photolithographic and etching methods that are used to make electronic integrated circuits.
Fiber Optic V-Groove
New Data Sheet Coming Soon!
Arrays are manufactured using highly precision etched silicon wafer V-Groove technology providing exceptional control of fiber-to-fiber pitch and linearity, in conjunction with a silicon lid enabling sub-micron accuracy. The V-Groove chips provide a multi-fiber housing that is exceedingly lightweight, low profile and highly robust, designed for next generation high performance photonic devices.
The V-Groove array assemblies are available with Single Mode, Multimode and Polarization Maintaining (PM) fibers, precise passive alignment of individual fibers, fan-out arrays or fiber ribbons to standard industry connectors, custom fiber spacing and angled polish end-face in vertical or horizontal direction, hermetic seal and high temperature options. Designed and manufactured for a wide range of applications in Telecom, Data Transmission and Switching, as well as High Power Fiber-Coupled Diode Laser Arrays and a host of General Fiber Optic Instrumentation.
