Engineering Precision: Square Groove Quartz Substrates
Comprehensive metallurgical, optical, and mechanical specifications designed for OEM engineers, optical system architects, and global procurement divisions.
Micron-Scale Groove Profilometry
Unlike conventional wet-etched isotropic channels, our square grooves feature orthogonal 90° sidewalls manufactured via high-frequency ultra-precision diamond grinding and reactive ion etching (RIE). Groove width and depth tolerances are maintained within ±1.0 μm, preventing rotational misalignment in fiber array blocks and PLC splitters.
Sub-Nanometer Surface Roughness
Groove inner wall and bottom surface roughness reaches Ra ≤ 15 nm (optical grade polish). This eliminates micro-cracking and sub-surface damage (SSD), mitigating scattering loss in evanescent waveguide coupling and preventing localized turbulent flow or cell stasis in capillary microfluidic channels.
Thermal & Geometric Stability
Manufactured strictly with synthetic fused silica (JGS1) and electric fused quartz (JGS2), our substrates boast an ultra-low Coefficient of Thermal Expansion (CTE: 5.5 × 10⁻⁷ /°C). They maintain absolute dimensional integrity across extreme temperature gradients ranging from cryogenic states up to 1,100 °C.

Supply Chain Resilience
The Strategic Chinese Factory Advantage
Unifying high-purity raw quartz smelting, ultra-precision cold working, and automated QA under a single, direct-factory production corridor in Tianjin.
Complete Vertical Integration
From optical ingot slicing and double-sided lapping to 5-axis CNC diamond grooving and chemical polishing, our manufacturing steps remain entirely internal. Eliminating external subcontracting prevents tolerance stacking, cuts lead times by 40%, and guarantees comprehensive batch-to-batch traceability.
Superior Cost-Performance Ratio
Direct manufacturer procurement bypasses intermediary distribution tiers. Buyers leverage highly competitive tooling amortisation, rapid custom prototype turnaround (as fast as 5 business days), and cost-effective ramp-up for multi-thousand unit recurring commercial runs.
Advanced Metrology Infrastructure
Equipped with non-contact white light interferometers, Zygo laser interferometers, 3D laser confocal microscopes, and high-resolution coordinate measuring machines (CMM). Every square groove quartz substrate is delivered with full dimensional, profile, and surface roughness verification certificates.

Regulatory & Sourcing Integrity
Global Procurement Demands & Compliance Assurance
Fulfilling the rigorous regulatory, environmental, and intellectual property requirements demanded by Tier-1 photonics and medical conglomerates in North America, Europe, and Asia-Pacific.
RoHS, REACH & Conflict Mineral Standards
All fused silica and quartz formulations undergo strict screening to ensure zero hazardous heavy metals, complying fully with EU RoHS Directives (2011/65/EU) and REACH (EC 1907/2006). Comprehensive material declarations and CMRT sheets are provided to simplify your supply chain compliance audits.
Cleanroom Ultraclean Packing & Export
To prevent particulate contamination during international transit, components are processed through multi-stage ultrasonic degreasing, rinsed with 18.2 MΩ·cm deionized water, and sealed in Class 1000 cleanroom-grade nitrogen-purged ESD antistatic trays before vacuum sealing.
Strict NDA & IP Protection Protocol
Custom micro-groove patterns often carry proprietary optical coupling and fluidic IP. We maintain rigorous internal protocols, including isolated production lines, offline CAM processing, and legally binding bilateral NDAs to protect our global partners' intellectual property.
Market Evolution
Key Application Scenarios & Sector Trajectory
From standard telecommunication passive splitters to co-packaged optics (CPO) and quantum photonic circuits, explore how micro-grooved quartz enables next-generation engineering breakthroughs.
Co-Packaged Optics (CPO) & Fiber Arrays
As AI computing clusters drive data center interconnects beyond 800G and 1.6T, square groove quartz substrates serve as critical fiber retention beds. Their matched refractive index and CTE match silicon interposers, securing optical coupling fibers directly to PIC photonic integrated circuits with ultra-low insertion losses (<0.15 dB).
Organ-on-a-Chip & Droplet Microfluidics
Modern genome sequencing, PCR thermal cycling, and continuous flow chemistry demand inert, non-fluorescing fluid paths. Our polished quartz square channels offer non-reactive chemical stability against strong acids, bases, and organic solvents while facilitating clear confocal microscopy inspection.
Quantum Computing & Trapped-Ion Systems
Next-gen quantum hardware requires dielectrics with minimal microwave loss tangents and zero dielectric hysteresis. High-purity JGS1 square grooved substrates provide the ideal structural and optical support for RF electrodes, optical waveguide routing, and atomic trapping chambers under ultra-high vacuum (UHV).
Procurement Knowledge Base
Frequently Asked Questions (FAQ)
Quick, authoritative answers covering tolerances, tooling, lead times, and custom processing options.
What is the standard tolerance achievable for groove pitch and channel width?
We routinely maintain a channel width tolerance of ±1.0 μm and groove pitch (center-to-center distance) tolerance within ±0.8 μm. For ultra-precision applications, tolerances can be tightened to ±0.5 μm using specialized diamond wheel dicing and closed-loop optical feedback metrology.
How does a square groove compare to standard V-grooves for fiber alignment?
While V-grooves (traditionally chemically etched in silicon) center fibers through 2-point tangent contact, square grooves fabricated in quartz are optimal for polarization-maintaining (PM) fibers, ribbon fibers, and rectangular optical waveguides. They prevent fiber rotational twist and provide uniform adhesive bonding clearance across bottom and vertical planes.
Can you machine substrates from customer-provided material blanks?
Yes. While we stock full ingots of synthetic fused silica (JGS1), optical quartz (JGS2), and IR quartz (JGS3), we also regularly process specialized customer-supplied materials such as Corning 7980, Suprasil, fused sapphire, or proprietary laser-grade glass substrates.
What is the typical lead time for custom prototype samples?
Standard prototype fabrication turnaround ranges from 7 to 12 working days depending on groove geometry complexity and whether optical polishing of the groove floor is required. Rush engineering prototyping can be scheduled in as few as 5 business days upon CAD file approval.
