Why Are Shares of These 2 Optics Tech Companies Soaring?

By Matthew Benjamin – Mar 5, 2026 at 10:15AM ESTKey PointsLumentum and Coherent make advanced optics technologies critical to AI networks.Right now, there's a shortage of the laser components that these companies make.Despite these stocks' strong gains recently, investors would do well to take a closer look.Shares of optics technology companies Lumentum Holdings (LITE 2.75%) and Coherent (COHR 3.58%) soared this past Monday. Lumentum rose 12% during the trading session, while Coherent climbed more than 15%. What's going on with these two companies? And should investors consider investing in them? This past Monday morning, artificial intelligence (AI) chip manufacturing giant Nvidia announced plans to invest $2 billion in each of the two companies. Nvidia said that its deal with Lumentum is a multi-year strategic agreement to accelerate innovation in advanced optics technologies. It includes access rights to the company's advanced laser components. These are critical for scaling AI factories and improving the energy efficiency and resiliency of large-scale AI networks and data centers, according to the press release. Image source: Getty Images. Nvidia said that the agreement with Coherent is a purchase commitment with future access and capacity rights for advanced laser and optical networking products. The optical interconnects and advanced package integration that Coherent provides are foundational to the next phase of AI infrastructure because they can unlock ultra-high-bandwidth, energy-efficient connectivity across AI factories. Most of the money Nvidia is investing in the two companies is slotted for advanced research and development of their optics technologies. The two deals are part of Nvidia's ongoing strategy of building an ecosystem to support AI systems.

Analysts say there's a huge imbalance between demand for the high-tech laser systems and supply. Research firm TrendForce forecasts that worldwide shipments of optical transceivers like those produced by Lumentum and Coherent will grow 2.6 times this year over the 24 million units that were estimated to ship last year. The surge in demand for the lasers is already causing a "significant upstream bottleneck in laser light sources," according to the report. Nvidia is buying up the lion's share of the advanced laser systems. The share prices of both optics stocks receded a bit on Tuesday, as the entire market was rocked by the ongoing and escalating war in the Middle East, with the S&P 500 index down 2% in late morning trading.

Coherent has climbed 54% year to date, and Lumentum has nearly doubled, soaring 92% since the beginning of 2026. If Nvidia is pumping money into the two companies, mainly for research and development, both stocks are absolutely worth a look despite already robust gains this year.Read NextFeb 13, 2026 •By Harsh ChauhanPrediction: This Could Be the Best-Performing AI Chip Stock of 2026Feb 8, 2026 •By Joe TenebrusoWhy Lumentum Stock Soared This WeekJan 16, 2026 •By Harsh ChauhanThis Artificial Intelligence (AI) Stock Has Jumped 328% in 1 Year.
