Properties of the fiber reflection Mach-Zehnder interferometer with identical couplers.
Results are presented of a study of a fiber reflection Mach-Zehnder interferometer that is based on identical couplers. It has been found that, for couplers having splitting ratios within a certain range, it is always possible to switch all the light between transmission and reflection by varying the interferometer phase difference. Outside of this range, the device reflects only a small portion of the incoming light. Devices based on couplers with various splitting ratios are shown to be potentially suitable for a range of applications.
