Wolfspeed Inc. has commercially introduced its transparent silicon carbide (TSiC) technology, targeting applications in augmented reality (AR), quantum computing and advanced optics. The company’s optical-grade TSiC substrates are designed for low optical absorption and high wafer flatness. SiC’s high refractive index, low birefringence, hardness and thermal conductivity make it a potential material for AR waveguides, where it could support wider fields of view, improved image quality and more compact wearable devices. Wolfspeed said its development builds on more than 35 years of SiC experience, including LED technology and manufacturing high-purity semi-insulating (HPSI) wafers. The material also has potential applications in quantum computing. According to Wolfspeed, SiC crystals can host quantum bits (qubits), preserve their quantum states and transmit quantum information through light. The company said this combination of functions distinguishes SiC from many alternative materials. “Wolfspeed’s leadership in SiC 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 SiC.” 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, highlighted the material’s potential for AR waveguides. “SiC changes that equation. 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’s work on optical-grade TSiC technology is exactly the type of materials innovation that can finally unlock that potential.” Wolfspeed is advancing 200mm optical-grade substrates while developing 300mm TSiC technology for future market requirements. The company also cited its intellectual property portfolio as supporting its technology development.
