Designing Optical Fiber and Components

Key Capabilities

  • Experienced Design Engineers with Specialties in a Variety of Fields
  • Material Scientists Dedicated to Fluoride Glass Production, Research, and Development
  • Full Access to Fiber Draw Towers and ThorShop
  • Custom Design Capabilities for Unique Optical Fiber and Component Solutions

Our team of fiber design engineers combines their knowledge of optical fiber with experience in mechanical and optical design to produce innovative solutions for a variety of fiber optic applications. Our fluoride glass scientists design and manufacture preforms that we then draw into fluoride fiber. This broad knowledge base ensures the production of high-quality components to support our industry-leading portfolio of specialty optical fiber.

After a "raw idea" is introduced, our design engineering team collaborates with our manufacturing engineers on the design. The idea is fully developed and potential concerns are addressed prior to starting any design work. Once the design is finalized, engineers create a 3D model using SolidWorks for mechanical components or design and evaluate optics using Zemax. The team also has full access to our fiber draw towers and ThorShop, our onsite machine shop, which enhance our design capabilities. These steps ensure that new products are delivered to customers as quickly as possible.

Our Montreal Facility manufactures many of our Fiber Couplers and Wavelength Division Multiplexers (WDMs) in 2x2, 1x2, and 1x4 configurations. While Thorlabs offers a variety of wavelengths and splitting ratios, our streamlined process has the flexibility to create custom parts on request. These custom components can be single mode or multimode with operating ranges between 400 to 2300 nm. Custom packaging and labeling is available. Components can also be created using double-clad fiber, allowing for multimode pump sources to amplify single mode signals, among other applications. All of our standard and custom products are serialized and include an individual product data sheets to confirm their performance. For these data sheets, we typically test our fused-fiber components at room temperature without connectors; however additional performance specifications can be recorded on request. The video to the right shows the steps our skilled fiber technicians take to create these products.
