Vanishing Core Fiber Spot Size Converter Interconnect

The Go!Foton™ Interconnect (Go!Foton™ FSSC) is an in-fiber, spot size converting interconnect for convenient and efficient coupling of light from an optical fiber into a planar waveguide device, photodiode or other high numerical aperture (NA) waveguide. A vanishing-core fiber design allows light from a conventional low NA fiber to be coupled to another waveguide with much smaller mode field dimensions at high coupling efficiency. The Go!Foton™ FSSC can be used with an air gap but it also allows index-matching compounds to be used between the coupler and waveguide as opposed to microlens-based coupling in which an air gap is unavoidable. The Go!Foton™ FSSC is available in three basic polarization maintaining or polarizing variations:

  • FSSC-PL: Linearly polarizing tapered coupler
  • FSSC-PC: Circularly polarizing tapered coupler
  • FSSC-PM: Polarization maintaining tapered coupler

The Go!Foton™ FSSC products are endface coupled and are provided within an all-glass construct (Package A) or within a metal tube (Packages B and C). Either design is pigtailed with a PM fiber pigtail. Standard central wavelengths provided are 1550, 1310, 1060 and 980 nm. The technology is readily scalable, and other central wavelengths as well as custom mode field diameters can be provided. A coupler chuck with standard 6.35 mm (0.25”) outer diameter, for compatibility with standard mounts, is also available, in conjunction with the standard metal tube package (Package B).

Applications:

  • Planar waveguide device coupling
  • Photodiode coupling
  • Laser diode coupling
  • Nanostructure coupling
