Nondestructive characterization of fiber couplers by a local perturbation method
A technique for the nondestructive characterization of fiber couplers is demonstrated. A CO<sub>2</sub> laser beam is scanned along the coupler length inducing a local perturbation to the coupler eigenmodes. Information about the power evolution and the coupling-constant variation along...
