What are the advantages of using a (11-20) oriented lithium niobate substrate compared to (0001) or (10-10) orientations?
The (11-20) orientation is one of three routine orientations offered for this lithium niobate substrate, alongside (0001) and (10-10). The choice depends on the specific phase-matching requirements for nonlinear optical processes such as parametric oscillation or frequency doubling. The orientation tolerance is <0.5°, ensuring precise alignment for device integration.
Why is the surface roughness specification critical for device fabrication with this lithium niobate substrate?
This substrate is double-side polished with a surface roughness <5 Å, which minimizes optical scattering losses in waveguides and ensures high-quality interfaces for thin-film deposition or bonding. Such low roughness is essential for maintaining low propagation losses in integrated photonic and acousto-optic devices.
What is the significance of the Curie temperature (~1140°C) for this lithium niobate substrate in high-temperature applications?
The Curie temperature of ~1140°C marks the point above which lithium niobate loses its ferroelectric and piezoelectric properties. This high value ensures stable electro-optic and nonlinear optical performance up to elevated temperatures, making the substrate suitable for devices that experience thermal cycling or operate in high-power environments.
This 5 × 5 × 0.5 mm (11-20) LiNbO3 substrate is supplied as nonlinear optical grade material with double-side polished surfaces below 5 Å roughness and an orientation tolerance under 0.5°, supporting nonlinear and electro-optic device workflows. Its 0.4–2.90 μm transmission window and specified nonlinear coefficients suit frequency conversion applications, but the absence of stated MgO doping means high-power optical damage resistance should be reviewed before deployment.
Positive
- Nonlinear-grade LiNbO3 for electro-optic devices: Supplied as nonlinear optical grade material, this substrate is specified for parametric oscillators, frequency doubling, acousto-optic devices, and optical modulators, with a 0.4–2.90 μm spectral transmission window and stated nonlinear coefficients.
- Sub-5 Å polished surface with <0.5° orientation tolerance: Double-side polishing and a surface roughness below 5 Å, combined with an orientation tolerance below 0.5°, provide a device-ready substrate for optical and electro-optic workflows.
Trade-offs
- Optical damage threshold not MgO-enhanced: The product description lists MgO doping as a way to improve optical damage threshold; since this listing does not specify MgO doping, the supplied LiNbO3 should be evaluated for optical damage resistance before high-intensity or high-power operation.
- Configuration confirmation required before quotation: This standard unit is specified as 5 × 5 × 0.5 mm, (11-20) orientation, double-side polished, and a 10-piece box; coating, tighter tolerance, alternate orientation, or different sizes must be reviewed with technical sales before quotation.
