A noninterferometric optical fiber add–drop channel filter based on a mismatched twin-core photosensitive-cladding fiber and long-period fiber grating is demonstrated. With assistance from the fiber grating, codirectional spectrally selective cross coupling between the two cores can be realized with an efficiency of 90%.
