OF6804 Square Core Homogeneous Energy Optical Fiber

Square Core Homogeneous Energy Optical Fiber Description

The Square Core Homogeneous Energy Optical Fiber is engineered to provide a flat, uniform energy profile across its entire core. In contrast to conventional single-mode fibers (SMF), where most of the optical power is concentrated at the center, this fiber maintains an evenly distributed output within its square core. Such a design is advantageous in systems that require a stable, homogeneous beam, reducing hot spots and improving overall performance.

Key Features:

• Uniform Output: Produces consistent energy delivery across the core, minimizing intensity variations.
• Square Geometry: Facilitates beam shaping and homogenization in laser applications.
• High Transmission: Optimized for low signal loss and reliable long-term operation.
• Robust Construction: Excellent thermal and mechanical stability under high-power or industrial use.

Square Core Homogeneous Energy Optical Fiber Applications

• Laser Material Processing
• Biomedical and Surgical Laser Systems
• Precision Measurement and Sensing
• Optical Coherence Tomography (OCT)
• Laser Illumination Systems

Square Core Homogeneous Energy Optical Fiber Packaging

Products are shipped in packaging appropriate to size and fragility:

• Small items secured in PP boxes
• Larger components in custom wooden crates
• Additional cushioning materials ensure safe transport

Standard options include carton, wooden box, paper barrel, iron barrel, or fully customized solutions.

Structure of Optical Fiber

Core

• Position: Located at the center of the optical fiber.
• Material: High-purity SiO₂, doped with trace amounts of GeO₂ or P₂O₅ to increase the refractive index (n₁), enabling light signal transmission.

Cladding

• Position: Surrounds the core.
• Material: High-purity SiO₂, with trace dopants such as B₂O₃ used to slightly lower the refractive index (n₂) so that it is slightly less than that of the core. This ensures that the light signal remains confined within the core for transmission.

Coating Layer

• Position: The outermost layer of the optical fiber.
• Structure and Material: Includes a primary coating, a buffer layer, and a secondary coating.

a) The primary coating is typically made of acrylate, silicone, or silicone rubber.

b) The buffer layer generally consists of a high-performance filling gel (for water resistance).

c) The secondary coating is usually composed of high polymers such as polypropylene or nylon.

• Function: To protect the optical fiber from moisture and mechanical abrasion, while also enhancing its mechanical strength and flexibility. This extends the service life of the fiber.

Customization Options

Stanford Optics offers flexible customization of core size, numerical aperture, coatings, and connector types. Square-core fibers can also be adapted into specialized fiber-optic devices. Evaluation samples are available for testing before volume orders.
