Precision Quartz V-Groove Substrates

BYNET precision quartz V-groove substrates are designed for positioning and aligning optical fibers in fiber array assemblies, optical communication components, and micro-optical packaging applications.

The substrates feature accurately defined V-shaped channels that provide mechanical positioning references for individual optical fibers. Single-channel and multi-channel configurations can be evaluated according to specific fiber dimensions, groove spacing, and assembly requirements.

Precision V-Groove Structures for Optical Fiber Alignment and Fiber Array Assemblies

Product Overview

Quartz V-groove substrates are precision glass components used to position optical fibers during fiber array assembly and optical packaging.

Each V-shaped groove provides two inclined contact surfaces to support an optical fiber. In multi-channel configurations, the relative groove positions define the nominal spacing between adjacent fibers.

The final fiber position depends on the fiber diameter, groove geometry, manufacturing tolerances, and assembly method.

BYNET offers precision quartz groove components and can review custom V-groove specifications based on customer technical drawings.

Key Features

V-Shaped Fiber Positioning

The V-shaped channels provide defined mechanical contact surfaces for optical fiber placement and alignment.

Single and Multi-Channel Configurations

Different groove arrangements can be evaluated for single-fiber positioning and multi-fiber array assemblies.

Quartz Glass Substrate

Quartz glass provides low thermal expansion and dimensional stability, making it suitable for consideration in precision optical assembly applications.

Application-Specific Groove Geometry

Groove pitch, angle, depth, and substrate dimensions can be specified according to the fiber arrangement and assembly requirements.

Drawing-Based Customization

BYNET can review requests for customized V-groove dimensions, channel counts, substrate sizes, and dimensional tolerances based on technical drawings.

Applications

Optical Fiber Array Assemblies

Precision V-groove substrates can be used as positioning components for arranging multiple optical fibers with defined nominal spacing.

PLC Splitter Packaging

V-groove structures may be incorporated into compatible fiber array assemblies used in planar lightwave circuit (PLC) splitter packaging.

Photonic Integrated Circuit Packaging

Customized V-groove substrates can be evaluated for fiber positioning in optical assemblies designed to interface with photonic integrated circuits.

Micro-Optical Component Assembly

Quartz V-groove substrates can serve as mechanical positioning components in compatible micro-optical systems requiring controlled fiber arrangements.

Custom Fiber Alignment Fixtures

Single-channel and multi-channel configurations can be considered for specialized fiber positioning and assembly fixtures.

V-Groove Design and Fiber Selection

Selecting a suitable quartz V-groove substrate requires consideration of several geometric parameters.

Groove Pitch

Groove pitch is the center-to-center distance between adjacent V-shaped channels. It is an important parameter for defining fiber spacing in multi-channel arrays.

V-Groove Angle and Depth

The groove angle and depth affect how an optical fiber contacts the inclined surfaces and where the fiber center is positioned relative to the substrate.

Fiber Diameter

The groove geometry should be selected according to the actual fiber cladding diameter and its dimensional tolerance.

Groove Positioning Accuracy

Applications requiring precise fiber spacing should specify adjacent groove pitch tolerance, cumulative pitch tolerance, and other relevant positional requirements.

Assembly Method

The final positioning performance also depends on the fiber fixation method, any cover substrate, adhesive application, and assembly tolerances.

Frequently Asked Questions

Q1: What are quartz V-groove substrates used for?

Quartz V-groove substrates are used to position and align optical fibers in fiber array assemblies, micro-optical packaging, and other precision optical components.

Q2: What is groove pitch?

Groove pitch is the center-to-center spacing between adjacent V-shaped channels. It helps define the nominal arrangement of optical fibers in a multi-channel array.

Q3: Can these V-grooves accommodate 125 μm optical fibers?

V-groove structures can be designed for fibers with a nominal 125 μm cladding diameter. Actual compatibility depends on the groove geometry, fiber tolerance, and assembly requirements.

Q4: Can BYNET provide multi-channel V-groove substrates?

BYNET can review multi-channel V-groove requirements according to customer drawings, including groove count, pitch, substrate dimensions, and positional tolerances.

Q5: Can V-groove dimensions be customized?

Custom groove pitch, angle, depth, width, and substrate dimensions can be evaluated based on technical drawings and manufacturing feasibility.
