The substrate requires cleanroom-grade handling to prevent surface contamination that degrades optical performance. Orientation tolerance below 0.5° and surface roughness below 5 Å must be preserved to maintain nonlinear optical and electro-optic functionality.
- Surface Integrity Constraint: Single-side polished surface must be protected from scratches, dust, and chemical residues to avoid scattering losses in optical applications.
- Orientation Tolerance Constraint: Crystallographic orientation within 0.5° must be verified before use to ensure phase-matching conditions for parametric or frequency-doubling processes.
Inspect each substrate for surface defects and orientation markings before deployment in optical or electro-optic setups. Clean and mount the substrate using non-contact methods to preserve surface quality and alignment.
Required Equipment: Cleanroom-grade tweezers or vacuum wand, Optical microscope with calibrated reticle, Lint-free cleanroom wipes and optical-grade solvent
- Inspect substrate surface
Examine the polished side under an optical microscope for scratches, pits, or particulate contamination before any processing step. - Clean substrate surface
Wipe the unpolished side with a lint-free wipe wetted with optical-grade acetone or isopropanol to remove organic residues. - Mount substrate in holder
Secure the substrate by its edges using a cleanroom-grade vacuum wand or spring-loaded holder to avoid contact with the polished face. - Verify orientation alignment
Confirm the (10-10) orientation marking aligns with the intended optical axis within the specified 0.5° tolerance using a goniometer or alignment fixture. - Store unused substrates
Place unused substrates in a sealed, anti-static container with desiccant to prevent moisture adsorption and surface degradation.
How does the single-side polished finish on this 10×10×0.5 mm LiNbO3 substrate affect its suitability for nonlinear optical applications compared to double-side polished substrates?
This substrate is single-side polished with a surface roughness <5 Å, which is sufficient for many nonlinear optical and electro-optic device workflows where only one optical surface requires high quality. For applications requiring both sides polished—such as Fabry-Pérot cavities or transmission-mode devices—double-side polishing is listed as a routine processing option. The orientation tolerance <0.5° ensures consistent phase matching regardless of polish configuration.
What are the key considerations when selecting the (10-10) orientation for lithium niobate substrates in acousto-optic or electro-optic modulators?
The (10-10) orientation is one of three routine orientations offered alongside (0001) and (11-20). For electro-optic modulators, the relevant electro-optic coefficients are γ13=9, γ22=3.4, and γ33=31 pm/V, and the refractive indices are no=2.286 and ne=2.203 at 632.8 nm. The orientation tolerance is <0.5°, which is critical for maintaining phase matching in nonlinear interactions. The specific orientation also affects the effective nonlinear coefficient and acoustic wave propagation direction.
Does this lithium niobate substrate include MgO doping to improve optical damage threshold?
The product description lists MgO doping as a method to improve optical damage threshold, but this specific substrate (model AF-LN-10ASP) is not explicitly stated to be MgO-doped. The standard material is nonlinear optical grade LiNbO3 grown by the Czochralski method. For MgO-doped variants or custom doping requirements, specifications should be confirmed with the manufacturer before quotation.
This 10 × 10 × 0.5 mm (10-10) single-side polished LiNbO3 substrate (Atomfair AF-LN-10ASP) is evaluated for nonlinear optical and electro-optic device use: it offers a 0.4–2.90 μm transmission window, <0.5° orientation tolerance, and <5 Å surface roughness in a 10-piece box, with single-side finish and coating/tolerance confirmation as the main integration variables.
Positive
- Nonlinear optical grade LiNbO3: Czochralski-grown trigonal LiNbO3 with nonlinear coefficients d33 = 34.45, d31 = d15 = 5.95, and d22 = 13.07 pm/V supports parametric oscillation, frequency doubling, acousto-optic, and optical modulator workflows.
- Defined orientation and surface quality: The (10-10) orientation is held to <0.5° tolerance with <5 Å surface roughness, providing a consistent crystalline reference plane for device fabrication and optical alignment.
Trade-offs
- Single-side polished only: This substrate is supplied with only one polished face; transmission-mode or through-beam optical setups may require additional polishing or surface selection because double-side polished parts are listed as routine processing elsewhere.
- Coating and tolerance must be specified before quotation: Atomfair requires confirmation of coating and tolerance requirements prior to quoting; buyers should not assume this listing includes customized optical coatings or tighter-than-listed tolerances, so those needs must be declared upfront.
