SICC (Shandong Tianyue)

Silicon-carbide waveguide wafers

Published by FyncaResearch checked How we research

Where it fits in smart glasses

300 mm SiC optical-waveguide wafers for AR glasses (Semicon China 2025); its 2025 annual report cites a July 2025 strategic cooperation with Shanghai Aolai Micro-Nano Optics and initial AR/VR applications with unnamed optics customers; optical-grade products still in R&D and customer validation (company, Mar 2026).

What the evidence establishes

Upstream enabler

Upstream enabler: SICC’s 2025 annual report cites initial AR/VR applications with unnamed optics customers and a July 2025 cooperation with Shanghai Aolai Micro-Nano Optics.

Materials, substrates, equipment or foundry capacity behind glasses components. This is not a component supplier or an established smart-glasses revenue stream.

How we knowDisclosed The company’s own filing, release, annual report, product page or investor record describes the smart-glasses role. Where customers are unnamed, the listing says so.

Keep in perspective

Optical-grade products were still in R&D and customer validation (Mar 2026), with unnamed customers.

Specialist business exposure. This describes the breadth or role of the business; it is not an investment rating. A smart-glasses product, design-in or partnership does not by itself establish material glasses revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

High-index waveguide plate

Light bounces along the plate by total internal reflection. A higher index allows a wider field of view: optical glass is about 1.8-2.0, silicon carbide about 2.6-2.7.

Scope of the company links: Upstream wafer suppliers that market high-index glass, polymer or SiC for AR waveguides. SICC reports initial AR/VR use with unnamed optics customers, still in customer validation; none names a shipping glasses program. The reflective waveguide glass in Meta Ray-Ban Display is reportedly SCHOTT’s (private).
