Thin Film Lithium Niobate (TFLN) wafers refer to engineered substrates that feature a nanoscale thin layer of lithium niobate (LiNbO₃) bonded onto an insulator, typically silicon dioxide, and supported by a silicon handle wafer. These wafers retain the excellent optical, electro-optic, and nonlinear properties of bulk lithium niobate while offering superior scalability, integration, and performance uniformity for photonic device fabrication.

TFLN wafers are the foundational material for manufacturing next-generation photonic components, including high-speed optical modulators (phase and intensity), frequency converters, and quantum photonic devices. Compared to traditional bulk LiNbO₃ substrates, TFLN wafers enable lower optical loss, tighter confinement of light, and compatibility with photonic integrated circuit (PIC) platforms. The market for TFLN wafers is still developing, with a small number of global suppliers providing 4-inch, 6-inch, and emerging 8-inch wafers for both research and commercial applications in optical communications, LiDAR, and quantum technologies.

TFLN Wafers represents a breakthrough substrate for advanced photonic integration. It consists of a nanometer-scale lithium niobate (LiNbO₃) layer bonded onto an insulating carrier, such as SiO₂ or glass. This thin-film structure offers strong optical confinement, high electro-optic coefficient (r33), and ultra-low propagation loss, making it ideal for high-speed optical modulators and next-generation integrated photonic circuits.

TFLN wafers are mainly produced in 4-inch  and 6-inch formats. The industry is rapidly transitioning to 6-inch due to better compatibility with existing CMOS and silicon photonics foundries. Jinan Jingzheng Electronics stands out as one of China's most commercially advanced TFLN wafer manufacturers. With a focus on 4-inch  =and 6-inch  bonded wafers and reliable output, it supports domestic and international customers in modulators and photonics research. Its route favors mechanical exfoliation combined with direct bonding, balancing yield and cost.

Optical communication modulators, especially for 400G/800G+ coherent links in AI and data center interconnects, are the primary commercial application of TFLN wafers. Compared to conventional bulk LiNbO₃ devices, TFLN-based modulators offer ultra-compact footprint, high bandwidth (>60GHz), low drive voltage, and superior scalability. TFLN is also gaining attention in optical resonators, acousto-optic modulators, frequency combs, and quantum photonic chips.

Looking forward, key trends in the TFLN wafer market include:

A transition toward 6-inch and even 8-inch wafers for improved yield and scalability;

Formation of a foundry ecosystem, particularly in China, integrating wafer suppliers, photonic fabs, and device/system companies;

Increasing demand driven by AI, quantum, and high-speed optical interconnect markets.
