This document outlines the technical constraints for handling the Atomfair lithium niobate crystal substrate. The substrate is sensitive to surface contamination and mechanical damage, requiring careful handling and storage.
- Surface Integrity Constraint: The polished surface must be protected from contact with particulates or abrasive materials to maintain the specified surface roughness of less than 5 Å.
- Environmental Sensitivity: The substrate should be stored in a clean, dry environment to prevent surface contamination or moisture adsorption that could affect optical performance.
- Orientation Verification: The crystallographic orientation tolerance of less than 0.5° must be verified before use in critical optical applications.
This procedure describes the safe handling and preparation of the lithium niobate crystal substrate for optical or electro-optic device integration. Proper handling is essential to preserve surface quality and prevent damage.
Required Equipment: Cleanroom-grade gloves, Vacuum tweezers, Cleanroom wipes
- Inspect the substrate
Inspect the substrate for any visible damage or contamination upon removal from its packaging. - Handle with clean tools
Handle the substrate using cleanroom-grade gloves or vacuum tweezers to avoid direct contact with the polished surface. - Clean the surface if necessary
Clean the substrate surface with a cleanroom wipe and an appropriate solvent if any particulate contamination is observed. - Store in a protective container
Store the substrate in a clean, dry, and protective container when not in use to prevent environmental damage.
What are the practical differences between single-side polished and double-side polished LiNbO3 substrates for nonlinear optical device fabrication?
Single-side polished substrates, like this 5×5×0.5 mm (10-10) variant, provide one optically smooth surface (roughness <5 Å) suitable for applications where only one side requires optical quality, such as when the substrate is mounted or bonded. The product description lists double-side polishing as a routine processing option, indicating that both surfaces can be polished to <5 Å roughness if required. For devices like optical modulators or waveguides that need both surfaces optically flat, double-side polished substrates are recommended.
How does the (10-10) orientation of this LiNbO3 substrate compare to (0001) and (11-20) orientations for electro-optic applications?
The (10-10) orientation is one of three routine orientations offered, alongside (0001) and (11-20). The electro-optic coefficients (γ13=9, γ22=3.4, γ33=31 pm/V) are material constants, but the effective electro-optic response depends on the crystal orientation relative to the applied field. The orientation tolerance is <0.5°, ensuring precise alignment. For specific device geometries, the optimal orientation may vary; technical support can assist in selection.
Is this LiNbO3 substrate MgO-doped, and what is the impact of MgO doping on optical damage threshold?
This specific product is not described as MgO-doped; it is listed as nonlinear optical grade LiNbO3. The product description notes that MgO doping is a method to improve optical damage threshold, which is critical for high-power applications such as frequency doubling or parametric oscillators. If a higher damage threshold is required, MgO-doped variants should be requested during quotation.
This Atomfair 5×5×0.5 mm LiNbO3 substrate with (10-10) orientation and single-side polish provides high nonlinear optical coefficients and broad spectral transmission for nonlinear and electro-optic applications, but the single-side polish and fixed orientation impose constraints on experimental flexibility.
Positive
- High nonlinear optical coefficients: With d33 = 34.45 pm/V, d31 = d15 = 5.95 pm/V, and d22 = 13.07 pm/V, this substrate enables efficient frequency doubling and parametric oscillation.
- Broad spectral transmission: Transmission from 0.4 to 2.90 μm covers visible and near-infrared wavelengths, suitable for a wide range of nonlinear and electro-optic applications.
Trade-offs
- Single-side polished surface: Provided with single-side polish only, which may not meet the requirements of applications that need double-side polished surfaces for optical path symmetry or interferometric setups.
- Fixed (10-10) orientation: This substrate is cut to a single (10-10) orientation, restricting its use to applications that require that specific plane; other orientations are not available in this product variant.
