In this article, we will discuss: 12 Best Photonics Stocks to Buy Now.
On April 15, Bloomberg reported that Italy had given 2D Photonics Group €211 million to improve AI data center processing and support domestic startups. The company announced that its Camgraphic subsidiary will develop graphene-based photonics and construct a pilot manufacturing plant near Milan to transition from research to production. CEO Ben Jensen stated, “Compute keeps getting faster, but data movement hasn’t kept pace,” adding that graphene optics can move more data with less power.
According to Bloomberg, silicon photonics uses light to carry data, which is faster and more efficient than copper, whereas 2D photonics tries to improve performance with graphene. Demand for data center technologies is increasing as big US technology companies invest hundreds of billions of dollars in AI infrastructure. Lumentum’s order books are full until 2028, and Nvidia has invested $2 billion in both Lumentum and Coherent. 2D Photonics stated that the European Commission approved the grant as state aid.
