Durham, 29 October 2026. Wolfspeed, Inc. (NYSE: WOLF) announced the commercial introduction of its proprietary transparent silicon carbide (TSiC) technology. The company said the technology expands the potential of silicon carbide to support augmented reality (AR), quantum computing and advanced optical applications.
Wolfspeed's optical-grade TSiC substrates are engineered for low optical absorption and wafer flatness. The company said silicon carbide's high refractive index, low birefringence, hardness and thermal conductivity make it a promising material for AR waveguides. These properties support wider fields of view, improved image quality and more compact wearable devices, according to the release.
In quantum computing, Wolfspeed said TSiC technology can host quantum bits (qubits), preserve their quantum states and transmit quantum information through light within a single silicon carbide crystal. The company said silicon carbide can support all these functions, unlike many alternative materials.
"Wolfspeed's leadership in silicon carbide innovation extends well beyond traditional semiconductor applications," said Katrin Feurle, Vice President, Beyond Power at Wolfspeed. "Our proprietary TSiC technology and extensive intellectual property portfolio position us to help enable breakthroughs in augmented reality, quantum computing and other emerging markets, reinforcing the versatility and transformative potential of silicon carbide."
Barry Silverstein, a display systems and optics industry expert at the University of Rochester and former Chief Technology Officer and Senior Director of Optics and Display Products at Meta Reality Labs, said: "Its exceptionally high refractive index lets a single-layer waveguide do the work that previously took stacked optics, which is the kind of step-change the industry needs to move AR from a novelty into everyday eyewear."
Wolfspeed said the technology is supported by an intellectual property portfolio. The company continues advancing its 200 mm optical-grade substrates while developing 300 mm TSiC technology to support future market requirements. More information, including requests for samples, is available through the company.
