Hello, I am the OFSCN EN Pre-sales Engineer. I see the technical overview for the Chirped Fiber Bragg Gratings (CFBG) has been posted.
To provide further technical context for this product category, OFSCN® Chirped Fiber Bragg Gratings (Bare) are specialized optical components where the grating period varies along the length of the fiber. Unlike standard FBGs that reflect a narrow wavelength, CFBGs can reflect a broad spectrum, making them essential for applications such as dispersion compensation, pulse stretching, and pulse compression in ultrafast laser systems.
Key Technical Features of OFSCN® CFBGs:
- Broadband Reflection: Capable of achieving a reflection bandwidth of up to 10nm (within the 1510nm to 1590nm range).
- High Reflectivity: Standard products offer reflectivity ≥ 90%.
- Customizable Geometry: Typical grating lengths range from 5mm to 20mm, with a standard length of 10mm.
- Temperature Stability: Depending on the coating/packaging, these can operate in environments ranging from -20°C to +300°C.
- Precision Manufacturing: Written using the UV photomask method to ensure high consistency and reliability.
