کوپلینگ فیبر به فیبر تک حالته – کامسول

Focusing a laser beam onto the tip of a single mode fiber is a common way to couple light. To achieve a good coupling efficiency, the spatial mode of the light field has to match the spatial model of the fiber. In this model, we use the Beam Envelopes Method to compute a small free space fiber-fiber coupling. The coupling efficiency depends on the position of the coupling lenses.
