Hi all,

In oder to calculate coupling efficiencies for a single mode fiber (Anlysis>Fiber Coupling>Single Mode Coupling) in the sequential mode, required specifications for fibers are numerical apertures and relative positions/angles to light sources. To my knowledge, a calculation of the fiber coupling requires a core radius and/or mode field diameter (MFD) as well as numerical apertures. I was wondering if we could get the coupling efficiency even without knowing the core radius or MFD values of single mode fibers in OpticStudio. Please correct me if I’m wrong.

Your help would be highly appreciated.

Thanks.
