So just to get us thinking more about POET's optical interposer and the VCSEL market.

Poet's optical interposer has applications in a wide range of high-growth markets, primary among them being high-performance computing, networking, optical transceivers, and transponders and automotive LIDAR systems. This platform technology is applicable to both gallium-arsenide- (GaAs) and indium-phosphide-based optical components. Optical engines for single mode transceiver modules represent the initial high-volume application for Poet's optical interposers.

It is worth thinking about. An efficient way to connect the VCSEL/VCSEL array to silicon.

I was going to talk about a pathway to optical clock distribution of silicon using the dielectric waveguide but one step at a time.
