Jeunke, regarding this Yves quote, - Last week’s PR was a breakthrough in Reliability and resistance to O2: the tests were conducted on thin films, based on work requested for aTier-1 Telco customer and the results, as noted were very, very good.

Do you remember when ASTS got a deal with AT&T, check out their chart, it has moved from about $2 into the $50s now, and check their financials as well, still very little Revenues yet for ASTS!! LWLG will get similar deals with MULTIPLE Tier 1's on the road to Ubiquity!!

Thin-Film LiNbO3 (TFLN) versus LWLG Electro-optic Polymers

Performance

Thin-Film LiNbO3 (TFLN)
- r33 intrinsically capped at ~ 31 pm/V at 1310 nm
- n = 2.2, er = 30 (high dispersion across frequencies)

LWLG Electro-optic Polymers
- No intrinsic cap on r33 (> 200 pm/V at 1310 nm easily achieved)
- n ˜ 1.9, er ˜ 3-6 (low dispersion across frequencies)

Integration

Thin-Film LiNbO3 (TFLN)
- Integration with Si/SiN very low yielding & basically still in R&D stage
- Limited wafer size (150 mm)
- Large device footprint (sub-cm scale)
- High material cost w/ only one supplier (NanoLN)

LWLG Electro-optic Polymers
- Fully Si compatible
- Easily scalable to 300 (+) mm wafer
- Very small device footprint (sub-mm scale)
- Low material cost

Processing

Thin-Film LiNbO3 (TFLN)
- Thin film uniformity becomes difficult as wafer size scales up
- Specialized processing/tools needed – leads to higher costs
associated with processing, QC, etc.

LWLG Electro-optic Polymers
- Spin-coating produces films with high uniformity
- No specialized processing/tools needed (completely compatible
with existing Si foundry processes/tools) – reduces costs
associated with processing, QC, etc
