| Evanescent-field coupling | Electrical Engineering | The coupling between two wave-guides, such as an optical fiber or an integrated optical-circuit (IOC), in which the waveguides are held parallel to each other in the coupling region, with the evanescent waves on the outside of one of the waveguides entering the coupled waveguide, bringing some of the light energy with it into the coupled waveguide.
