INTERPOSER WAFERS

Interposer wafers offer the ability to combine the advantages of photonic and electronic components to enable complex, compact and energy-efficient photonic integrated circuits (PICs).

Active Interposer

We use advanced waveguide fabrication methods that improve silicon waveguide propagation loss to < 0.5 dB/cm while the silicon nitride waveguide propagation loss is < 0.35 dB/cm. Learn more

Electronic Interposer

The electronic interposer is a silicon (Si) wafer used for enabling 2.5D integration of photonic and electronic integrated circuits for advanced packaging. Learn more
