Dear all,

I would like to investigate the single-mode fiber coupling efficiency using Physical Optics Propagation in function of the fiber tilt angle. I would like to use the Universal Plot to see its sensitivity, and afterwards see its effect during a complete tolerance analysis together with other tolerances (both in the RSS estimate as well as in a Monte-Carlo simulation).

However, it seems that either using a coordinate break before the fiber surface, or using the ‘Tilt’ surface as the final surface (as was done in the angled-fiber article but without using POP) does not affect the POP fiber coupling calculation. The ‘tilt about X/Y (deg)’, inside the POP ‘fiber data’ can of course be used to set the tilt, but this value can (as far as I’m aware) not be used for plotting or tolerancing.

Is there some other way to easily plot and tolerance this fiber tilt when using POP, without having to use a custom macro or ZOS-API code?

Thanks for any input,

Best regards,

Indy
