Engionic Femto Gratings

What Engionic Femto Gratings does

engionic Femto Gratings GmbH, founded in 2013 in Goslar, Germany, is the first commercial supplier worldwide of femtosecond-laser-written Fiber Bragg Gratings (FBGs). The company uses a proprietary infrared femtosecond-laser point-by-point writing process to inscribe FBGs directly through fiber coatings without stripping or recoating. Because the non-linear process is independent of fiber material composition, FBGs can be written into pure silica core fibers, radiation-hard fibers, sapphire fibers, and other specialty fibers without doping requirements. The resulting Type II gratings withstand temperatures up to 1,000°C—roughly four times the threshold of conventional UV-inscribed FBGs—and are produced on a coil-to-coil fully automated platform with inline quality control, reporting, documentation, and strain testing.

The product portfolio spans Single FBGs (standard Femto and premium FemtoPlus variants offering 0–5pm polarization and <0.2dB scattering losses), FBG Arrays in WDM, TDM, and combined WDM/TDM configurations (supporting over 2,000 sensors per cable with minimum 2mm spacing), and FBG Specialities including chirped gratings, wavelength lockers, Fabry-Perot cavities, and DWDM telecom filters. Supporting offerings include a comprehensive fiber and coating range and a Customer Individual High Volume Production Lines service that co-develops dedicated manufacturing capacity with anchor customers under multi-year programs with defined efficiency targets within a 12-month ramp-up.

Revenue is generated through hardware sales of FBG products and contracted high-volume production-line development. The go-to-market combines sales-led direct engagement via a Berlin sales office with an online FBG configurator that enables registered customers to calculate pricing, place orders, and reorder. The company serves four vertical segments—industrial sensing (wind turbine monitoring, structural health monitoring, aerospace), medical sensing, telecommunications (DWDM filters, laser stabilization), and harsh-environment/subsea applications (nuclear, subsea oil and gas)—and holds ISO 9001:2008 certification. It operates as a wholly-owned subsidiary of family-owned holding company engionic AG.

Core offering

engionic Femto Gratings manufactures femtosecond-laser-written Fiber Bragg Gratings (FBGs) and sells them as single FBGs, FBG arrays, and specialty FBGs for industrial and medical sensing applications. The company uses proprietary fs-laser point-by-point writing technology that inscribes gratings through fiber coatings without stripping or recoating, supporting standard and specialty fibers. It also develops customer-specific high-volume production lines for recurring FBG demands.

Product overview

Engionic Femto Gratings offers a comprehensive portfolio of femtosecond-laser-written Fiber Bragg Gratings (FBGs) as the first commercial supplier worldwide since 2013. The product line centers on Single FBGs (standard Femto and premium FemtoPlus variants), FBG Arrays (WDM, TDM, and combined WDM/TDM configurations), and FBG Specialities (chirped gratings, wavelength lockers, telecommunication filters, Fabry-Perot cavities). Supporting offerings include Customer Individual High Volume Production Lines for exclusive large-scale manufacturing, Fibers and Coatings (diverse fiber types and temperature-resistant coatings), all powered by the company's industry-leading fully automated fs-laser production technology with inline quality control.
