Co-Packaged Optics

Diamond Solutions
for CPO

Ultra-high thermal conductivity diamond substrates for next-generation Co-Packaged Optics. Engineered to match industry-standard CPO component architectures.

Why Diamond for CPO?

Co-Packaged Optics place optical engines directly adjacent to switch ASICs, creating extreme thermal challenges that diamond solves.

Ultra-High Thermal Conductivity

Diamond instantly spreads heat from densely integrated optical engines and switch ASICs, far exceeding copper and aluminum nitride.

Sub-0.1K Temperature Uniformity

Critical for maintaining optical alignment in co-packaged modules. Eliminates thermal gradients across switch dies.

Custom Dimensions

Match industry-standard CPO component architectures. Custom DFM for any OEM footprint.

CPO Product Lines

Diamond substrates designed for specific CPO applications, matching industry-standard component architectures.

CPO Switch Baseplates

Cu-Metallized Diamond

Thermal baseplates for 51.2T/102.4T CPO switches. Cu routing for driver interconnects.

CPO Optical Engine Lids

Diamond IC Packaging Lid

EMI-absorbing lids for PIC/EIC chiplets. In-situ thermal sensing for real-time monitoring.

ELSFP Laser Submounts

Cu-Metallized Diamond

Multi-channel Cu routing for dense CW laser arrays. OIF-ELSFP-02.0 compatible.
