Chiral Photonics

Microforming

Chiral Photonics has established and refined precision glass forming and fabrication capabilities. Based on the application needs and designs, we create twisted and tapered chiral structures out of glass fibers and tubing with sub-micron accuracy to address photonic and mechanical applications ranging from lasers, filters and sensors to microscopic heat exchangers, micro-capillary array mixers and microfluidics. Capabilities include
 

  • Twisting to sub-micron pitch with sub-micron accuracy and continuous control
  • Tapering to desired profile shapes
  • Braiding of fibers and tubing of various shapes and sizes
  • Splicing of fibers and tubing with differing thermo-mechanical and/or optical transmission properties to achieve splice profiles and/or low loss photonic connections
  • 1D and 3D Photonic Modeling of photonic devices, including splices and taper profiles
