Question

I would like to simulate fiber-to-fiber coupling. How can I do this in OSLO?

Synopsis

Solution

"Fiber-to-fiber coupling is achieved by performing a series of steps in OSLO:

Model the end of the initial fiber as a beam waist using the "Source>>Paraxial Gaussian Beam (ABCD)" or "Source>>Skew Gaussian Beam" menu option. Using one of these analysis options, determining the size of the beam on surface number 1 of your optical system.
Input the size of the Gaussian (on the first surface) as the "sdgx" and "sdgy" parameters in the Paraxial Setup Dialog. Ensure that the size of the system aperture is oversized when compared with the Gaussian cross-section or your calculation will incorporate clipping of the Gaussian beam.
Perform a fiber coupling efficiency calculation using "Source>>Fiber Coupling..." menu option.

For more information about how to model Gaussian beams and fiber coupling in OSLO, please refer to the following documentation which is downloadable from the Lambda Research Corporation web site:
