LNOI (Lithium Niobate on Insulator) wafers are advanced photonic platforms based on ultra-thin lithium niobate (LiNbO₃) films (300–900 nm) bonded to insulating substrates (e.g., silicon, sapphire, or glass) via ion implantation and direct bonding techniques.
Key advantages include:
· Flexible sizes: Customizable 4–8-inch wafers with tunable film thickness (standard 600 nm, scalable to micro-scale).
· Heterogeneous integration: Compatible with silicon, nitride, and glass for monolithic integration of electro-optic modulators, quantum light sources, etc.
· ZMSH services: Wafer design, bonding process optimization, wafer-level fabrication (photolithography, etching, metallization), and turnkey solutions for prototyping to mass production.

1. Material Properties:
· High electro-optic coefficient (r₃₃ ≈ 30 pm/V) and wide transparency window (0.35–5 μm), enabling UV-to-MIR applications.
· Ultra-low waveguide loss (<0.3 dB/cm) and high nonlinearity for high-speed modulation and quantum frequency conversion.
2. Process Advantages:
· Sub-300 nm films reduce modal volume, supporting >60 GHz bandwidth modulators.
· Thermal expansion mismatch mitigation through bonding interface engineering (e.g., amorphous silicon layers).
3. Performance Comparison:
· vs. Silicon Photonics/InP: Lower power consumption (<3 V half-wave voltage), higher extinction ratio (>20 dB), and 50% smaller footprint.
1. High-Speed Optical Communications:
- Electro-optic modulators: Enable 800 Gbps/1.6 Tbps modules with >40 GHz bandwidth, 3× efficiency over silicon.
- Coherent modules: Heterogeneously integrated with silicon photonics for low-loss, high-reliability long-haul transmission.
2. Quantum Information Systems:
- Quantum light sources: Integrated entangled photon pair generators for on-chip quantum state manipulation.
- Quantum computing chips: Leverage LiNbO₃’s nonlinearity for qubit fabrication and fault-tolerant architectures.
3. Sensing & Imaging:
- Terahertz detectors: Non-cryogenic imaging with mm-resolution via EO modulation.
- Fiber optic gyroscopes: High-precision inertial navigation for aerospace.
4. Optical Computing & AI Acceleration:
- Photonic ICs: Ultra-low-latency logic gates and switches for parallel AI processing.
1. Core Services:
Wafer Customization: 4–8-inch LNOI wafers with X-cut/Z-cut orientations, MgO doping, and buried oxide layer thickness (50 nm–20 μm).
Heterogeneous Integration: Bonding with silicon, sapphire, or nitride for hybrid EO-optical chips (e.g., laser-modulator monoliths).
Fabrication Services: 150 nm UV lithography, dry etching, Au/Cr metallization, and wafer-level packaging/testing.
End-to-End Support: Design simulation (PIC Studio tools), yield optimization, and full-scale production.
2. Technological Trends:
Larger Wafers: Transition to 8-inch LNOI for cost reduction and capacity scaling.
Ultra-Thin Films: Develop <200 nm films to overcome short-wavelength absorption limits (visible-light applications).
Hybrid Integration: Bond with III-V materials (InP) for laser-modulator integration.
Smart Manufacturing: AI-driven etching parameter optimization to reduce defects (<1 defect/cm²).
1. Q: Is lithium tantalate the same as lithium niobate?
A: No. Lithium tantalate (LiTaO₃) and lithium niobate (LiNbO₃) are distinct materials with different chemical compositions (Ta vs. Nb) but share a similar crystal structure (R3c space group) and ferroelectric properties.
2. Q: Is lithium niobate a perovskite?
A: No. Lithium niobate crystallizes in a non-perovskite structure (R3c space group), differing from the canonical ABX₃ perovskite structure. However, it exhibits perovskite-like ferroelectric behavior due to its ABO₃-like oxygen octahedral framework.
