InPhase Corporate Overview
InPhase Technologies Inc was founded December 2000 and incorporated in January 2001, with offices in Longmont, CO.
Created to commercialize holographic media and holographic recording technologies developed at Bell Labs (Lucent)
Applying this technology to build products around removable media with potentially huge storage capacity, random access and high transfer rates
Page 5DL 03-06-03
InPhase IP portfolio

InPhase’s Tapestry™ Recording Material
Media is fabricated from independently polymerizable and compatible matrix and imaging components
In-situ formation of cross-linked matrix
Resin consists of matrix precursorsand imaging components
Writing chemistry is independent ofhost formation chemistry
Proprietary Two Chemistry Approach
In-situ matrix formation: thick, optically flat formats with good mechanical robustness
Cross-linked matrix: stable holographic gratings -long archival life
Compatible matrix and monomer systems: optical clarity and low levels of light scatter
Independent matrix and monomer systems: no cross-reactions- maximizes refractive index contrast.

100 Å
3” x 3”, 1 mm-thick media
Excellent optical quality & thick media
Proprietary DVD-like media fabrication method allows for
Routine fabrication of media with better than λ/4 / cm2
flatness enables high fidelity data storage and recovery

Physical View• Physically each page (hologram) takes the whole volume of the book• The thickness of the recording layer allows each page to be read out and stored
uniquely by changing the reference beam angle for each page.
Thickness of recordinglayer is ~1.5 mm

Current Drive Development Status:• We have built four Test Bed hardware platforms that are fully
operational Holographic recording machines.• We have demonstrated the recording and recovery of 600
holograms in one spot on the holographic media.• We have demonstrated accurate mechanical positioning of the
optical recording head on the disk media.• We have demonstrated partial interchange between two of the
Test Bed platforms.• All our control and data handling electronics (except for
interface) have been developed and are functional.• We have completed the design and simulations of the drive
optics and mechanics.
