16 Fiber Photonic-Plug

A fiber connector product for assembly of optical fibers with silicon photonics chip.

The product is optimized for transceivers and co-packaged optics stacks with high compatibility to flip-chip and reflow packaging processes.

Key Features

High assembly tolerance better than ±20µm / 1dB for assembling single-mode fiber ribbon to a silicon photonics chip.

Supports 16 fibers, silicon photonics packaging for transceiver (direct bonding) and co-packaged optics (detachable) products.

Uses Self-aligning optics for passive assembly protocols and supports high volume packaging using standard semiconductors manufacturing and packaging flows.

Supports wavelength division multiplexing (WDM) die stacking with surface-coupling geometries.

Incorporates wafer level optical elements for seamless integration of optical and electrical bumps.
