Single Mode Fiber-to-Fiber Coupling
Application ID: 75051
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.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabela de Especificações and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
