Photonic packaging for CPO

Production AI-interconnect CPO (2027-2030) is won by inorganic photonic-packaging platforms (TFLN, BTO/SiN, silicon nitride); polymer 2PP/xolography materials do not qualify

  • Bull
  • Closing
  • $29B by 2035

The callOptics is moving into the chip package; the inorganic modulator and fibre-attach layer underneath is where a merchant supplier can still win, and polymer loses.

Fig. 1The balance. Drivers and catalysts against restraints, each block sized by its weight; catalysts hang dashed because they have not happened yet, sized by their odds. It tips toward the drivers.
  1. D1Links inside the rack get too short and hot for copper, and pluggables at the faceplate run short on speed, reliability and yield at 2027 volumes.
  2. D2Foundries want drop-in electro-optic modulators, reworkable fibre attach and wafer-scale alignment, which they do not make themselves.
  3. R1Foundries insource once the process is de-risked, which is what COUPE is, and HyperLight's $80M from Taiwan's packaging ecosystem prices the merchant layer for absorption.
  4. R2No independent company in the layer is active today, and only 10-15% of scale-up links may migrate to CPO by 2030-31.
  5. C1A merchant foundry publishes a production-qualified BTO or lithium niobate tile in an open design kit, making ferroelectric modulators the CPO standard.Dec 2027

What changedthe record, newest first
  • 16 Jul 2026Co-packaged optics is industrialising around inorganic modulator materials; this quarter the flagship thin-film lithium niobate platform raised from the Taiwanese packaging and foundry ecosystem itself. The material-class question in optical interconnect looks increasingly settled in favour of the inorganics.
