Abstract

We demonstrate a novel fiber add-drop multiplexer based on a selective fused coupler consisting of a twin-core fiber and a standard telecommunication fiber and a single fiber Bragg grating. Loss as low as ~1.1 dB for the added and dropped channel is demonstrated with a potential to be as low as ~0.4 dB. Better than 30 dB isolation is also achieved between the dropped and added channels. The device is based on well-developed fused coupler and Bragg grating technology. Most importantly, the method is noninterferometric, which means it does not need critical alignment or trimming. The fused coupler and grating are completely decoupled and can be made separately
