Single-mode microstructured optical fiber

Description

Microstructured optical fiber made of undoped silica glass with a hexagonal arrangement of air holes in acrylate coating operating in a single-mode regime of propagation with almost ideal quality of output radiation over a wide spectral range

Application areas

  • Systems for delivery of high-power laser radiation
  • Multiwavelength data transmission systems
  • Mode-filter optoelectronic components
  • Systems for delivery of (ultra)short pulses
  • Devices for targeting and illumination with low angular divergence

*Other coating thicknesses on demand

**To ensure resistance to high (up to 300 °C) temperatures and aggressive conditions (high humidity, acids), it is possible to apply a metal (tin, lead) coating

***Measured for bending diameter of 16 cm
