$SIVE / $SIVEF - A 75-year-old Swedish chip company with 130 employees just became one of the most important suppliers in the entire AI infrastructure stack. The AI data center buildout is hitting a physical wall. Copper interconnects between GPUs are running out of bandwidth, dissipating too much heat, and burning too much power. Every hyperscaler roadmap from 2027 onward solves this by moving the optical-to-electrical conversion INTO the chip package itself. This is called Co-Packaged Optics (CPO). CPO needs three things: 1. An optical engine (the modulator chiplet) 2. A packaging platform (the interposer) 3. An external light source feeding the engine That third component is the bottleneck. It needs to be a high-power, multi-wavelength, continuously emitting laser array - specifically built on Indium Phosphide (InP). There are maybe 4 companies in the world that can make these at hyperscaler-grade quality. $SIVE is one of them. They're the only Western microcap pure-play. They ship from a 700m² cleanroom in Glasgow that can run over 2 million laser tests per month, with a second-source qualification underway at WIN Semiconductor in Taiwan to unlock real volume. I am going to give you a 5-post breakdown of where they sit, who's already using them, and why this could be the next $LITE - follow if you are interested. This will be posted through the next 2 days
