Coherent

Coherent Corp, (formerly II-VI Incorporated) is a major American producer of optical components, with a strong portfolio in laser technology for photonics and datacom. In fiscal year 2025, Coherent generated over $5.8 billion USD in revenues. Coherent has recently transitioned from 4" to 6" indium phosphide (InP) wafers - an industry first. It has also reportedly validated ultra-high powered (UHP) laser technologies for co-packaged optics (CPO). Coherent is also pursuing VCSEL's for use at 200G/lane applications. In this profile IDTechEx assesses these breakthroughs in the context of the wider datacom, AI, and photonics markets.

IDTechEx Technology Analyst James Falkiner recently attended SPIE Photonics West, where photonics company, Coherent, heavily sponsored the event. Coherent (formerly II-VI) acquired one of the world's largest pluggable transceiver firms Finisar, and continues to have a strong market share to this day.
