5. Fiber Interface Fiber Interface Optical “Heart” ~ 15% Fiber Interface ~ 85% Fiber Components All fiberoptic components have two parts: Optical “heart” which provides functionality Fiber Input/Output interface Optical “Heart” Manufacturing Cost Optical “heart” is only ~15% of the total cost of a fiberoptic component Fiber interface or “packaging” is ~85% of cost Companies have focused on optical “heart” and traditional packaging Property of Arrayed Fiberoptics Corporation

6. Planar Lightwave Circuit Fiber Waveguide GRIN Lens Lens Fiber Array Fiber Array Laser Diode GRIN Lens Why the high cost? Micro-Optics • All current technology involves individual fiber alignment • Sub-micron alignment is neccessary in many cases • Many expensive piece parts required • Fiberoptic components cost hundreds of dollars each

7. The Breakthrough:VFI – Vertical Fiber Integration • 1. Apply LARGE-SCALE semiconductor manufacturing technologies to fiber alignment • align 2 = align 20,000 • 2. Bond multiple wafers together to VERTICALLY create high-value 3-D FULLY integrated devices. • Passively insert fibers into pre-aligned high-precision sockets after singulation • Covered by multiple issued and pending patents The differentiator is full wafer-scale integration Property of Arrayed Fiberoptics Corporation

8. VFI Process Overview Bonding Singulation Fiber Incorporation Property of Arrayed Fiberoptics Corporation Wafer Alignment
