摘要：

A novel technique to determine the coupling length as a function of wavelength in directional couplers, especially in the case of weakly coupled, symmetrical directional couplers is described. The technique is illustrated by using Ag + -Na+ ion-exchanged directional couplers in BK7 glass. Application of this technique to asymmetrical directional couplers is also addressed.
