mode-multimode fiber concatenation structure

Here, we propose a novel all-fiber band rejection filter utilizing multimode-single mode-multimode (M-S-M) concatenated structure. The proposed filter consists of two identical multimode fibers (MMFs) and a conventional single-mode fiber (SMF) of a very small length, which is spliced between the MMFs. Since there is a core diameter difference between MMF and SMF, the cladding of the SMF are excited along with core modes and an interference loss between core mode and cladding modes is observed. By systematically adjusting the parameters of fibers of the proposed device, we show that the interference loss in the device can be utilized as a band rejection filter. © Anita Publications.
