  1. 1. March, 2010<br />
  2. 2. Management Team<br />Reid Rubsamen, President and CEO<br />A.B. Computer Science, Berkeley <br />M.S. Computer Science, Stanford <br />M.D. Stanford<br />Laboratory for Computer Science, MIT<br />Doctoral candidate 1989 - 1991<br />Founded Aradigm (IPO 1996)<br />Founded Flow Pharma 2002<br />Named inventor on 65 issued U.S. Patents<br />
  3. 3. Flow Focusing Technology<br />Liquid guided by “lens” of gas producing precision micro-jet<br />Jet does not touch sides of the hole<br />Immaculate Extrusion<br />
  4. 4. Flow Focusing Technology<br />Invisible “lens” of gas can be qualitatively demonstrated experimentally<br />
  5. 5. Flow Focusing Technology<br />Concentric needle configuration<br />Allows production of clad fiber or encapsulated microspheres<br />Cure early for fiber<br />Cure late for spheres<br />
  6. 6. Flow Focusing Technology<br />Steady state jet characteristics described by a formula<br />Dependencies are on liquid density, gas pressure drop and liquid flow rate<br />Patented Physics<br />
  7. 7. Molten Material ExtrusionFiber Production<br />Traditional optical fiber fabrication process<br />Pre-form is mounted in a tower and heated<br />Fiber is drawn down<br />
  8. 8. Molten Material ExtrusionFiber Production<br />No pre-form required<br />Core and cladding can be co-extruded<br />No heat or strain introduced by viscous fiber draw-down<br />Wide range of possible materials<br />
  9. 9. Fiber Optic Light Transmission<br />Traditional approach is via total internal reflectance (TIR)<br />Process is lossy and not phase preserving<br />Photonic bandgap (PBG) transmission allows potentially lossless, phase preserving light transmission<br />PBG fiber can be used to transmit very high energy laser light<br />Short lengths of PBG fiber have been produced but no process exists for kilometer length production<br />
  10. 10. PBG fiber is very high performance with ultra low loss<br />PBG fiber has specialty fiber roles e.g. can serve as a notch filter<br />Blaze founder Russell described simple structures for PBG transmission<br />
  11. 11. Potential Benefits of PBG Fiber<br />Long Haul Fiber<br /><< 0.1db loss/kilometer<br />Phase preserving<br />Broad band<br />Specialty Fiber<br />Transmission of high power laser light<br />Passive notch filter<br />
  12. 12. Potential Demand<br />Internet optical backbone capacity requirement<br />In-place internet optical backbone capacity<br />Bandwidth<br />Emergence of video-on-demand<br />Time<br />Bandwidth<br />Time<br />
  13. 13. Fiber Optic Applications<br /><ul><li>FF may be the only viable process for mass production of low loss PBG fiber</li></li></ul><li>Parallel Co-Extrusion<br />

  28. 28. Molten Glass Entering Open Nozzle<br />
  29. 29. Hollow Core Fiber Cross Section<br />Randomly selected hollow <br />fiber cross section. There <br />are still instabilities evident<br />in this early draw. The <br />ten micron diameter core<br />has good circularity and <br />concentricity, but the fiber <br />body is 10% elliptical. <br />Several hundred meters<br />of comparable fiber were<br />produced in this <br />experiment.<br />
  30. 30. Goal<br /><ul><li>Make kilometer lengths of precision, multicore PBG fiber and test performance</li></li></ul><li>Path To The Goal<br />
