Optical fibers are widely used in different applications; single-mode fibers especially play an important role in long-distance communications. Launching light into single-mode fibers can be a challenging task in practice. VirtualLab Fusion enables fast evaluation of fiber-coupling systems thanks to the physical-optics-based simulation techniques, fiber-related detectors, and many other helpful tools. For example, one can find the optimal working distance for coupling light into single-mode fibers, and compare the performance of different coupling lenses.

Optimal Working Distance for Coupling Light into Single-Mode Fibers

In this example, we select one commercially available lens and show how to find the optimal working distance to obtain maximum fiber-coupling efficiency using field tracing.

Comparison of Different Lenses for Fiber-Coupling

For the task of coupling light into a single-mode fiber, two commercially available lenses are selected and their performance is evaluated using the overlap integral.
