Abstract
A system for selectively adiabatically coupling electromagnetic waves from one waveguide to another waveguide is described. It comprises a first waveguide portion and a second waveguide portion having substantially different surface normal cross-sections. Portions thereof are positioned with respect to each other in a coupling region so that under first predetermined environmental conditions coupling of electromagnetic waves between the first waveguide portion and the second waveguide portion can occur and under second predetermined environmental conditions substantially no coupling of electromagnetic waves between the first waveguide portion and the second waveguide portion can occur. The system also comprises a fluid positioning means for selectively positioning at least a first fluid simultaneously overlaying both said first waveguide portion and said second waveguide portion in the coupling region thus selectively inducing first predetermined environmental conditions or second predetermined environmental conditions.
