Fiber Optics: How Fused Fiber Optic Couplers Work
... Up to this point we have tacitly assumed that a single transfer of energy has occurred from one fiber to the other. In reality, energy transfers back and forth between the two fibers many times over the coupling region (also called the Interaction Length). The transfer rate is a function of waveleng ...
