▲ [21p-A406-7] Characteristics of a Multimode-Single-mode-Multimode Fiber Concatenated Structure as Host of a Few All-fiber Devices
キーワード：Optical fiber sensor, Gain flattening filter, Band rejection filter
Over the past few years, fiber optic technology has exponentially grown as the demand for sensor and light signal transmission continues to increase. With these in mind, we worked out a host of all-fiber devices based on a concatenated multimode-single-mode-multimode (M-S-M) fiber structure aimed at a few potential applications in communication systems. We show that our device is versatile and can be utilized as a sensor as well as a gain-flattening filter (GFF). This M-S-M device can also work as a band rejection filter.
