Multi-core Photonic Crystal Fibre

Supercontinuum generation (SCG) in photonic crystal fibre (PCF) has been a focus of optics and photonics, and high-power superconducting light sources are favored for their high spectral power density. Multi-core PCF can not only further increase the effective mode field area, but also alleviate the thermal stress problem of discrete distribution among cores , further increasing the saturation threshold of operating power gain. In the application of high-p ower fibre laser, it can effectively reduce the impact of nonlinear effects.
  • High-power supercontinuum light source
  • Highly nonlinear optics
  • Large mode field area
  • High nonlinearity
  • Pure silica material
Cross Section
