New Features in VirtualLab Fusion for Fiber Optics

Fiber Coupling, Fiber Mode Sources, and Propagation Through Fibers

VirtualLab Fusion comes with new features for the modeling and design of systems for fiber optics. Based on linearly polarized (LP) modes and Gaussian-Laguerre solver techniques, we present:

  • The fiber source, which emits customer-selected weighted fiber modes,
  • The fiber coupling efficiency detectors, which provide the efficiency of the power transferred into multi-mode and single-mode fibers,
  • The fiber component, which enables the propagation of electromagnetic fields through fibers.

These new features significantly extend the physical-optics modeling and design capability of VirtualLab Fusion for fiber optics applications. This is demonstrated by examples such as:

  • Investigating the aberration effects on the fiber modes in the focal region,
  • Analyzing the field propagation through an optical system with fiber components,
  • Presenting a complete design workflow of the coupling system of either single-mode or multi-mode fiber, including lens system design and tolerance analysis.
