We demonstrate a new type of Mach-Zehnder interferometer by combining a nonadiabatic microtaper with a long period grating in the same stage of all solid photonic bandgap fibers. Meanwhile, the mode-coupling caused by the microtaper is indirectly verified by the interference with the long period gra...
