“…Therefore, environmental stabilization, UV trimming of individual paths, and identical couplers and gratings are essential for good device performance. A unique method for manufacturing a Mach-Zehnder OADM was developed by S.Bethuys et al [17].Dual Bragg grating MZI-OADM was written in a twincore fiber. The special twincore fiber is used to improve the balance of the interferometer.…”

This paper describes the design of Mach Zehnder Interferometer and reviews its applications in emerging optical communication networks. Mach Zehnder Interferometer is basically used to measure relative phase shift between two collimated beams from a coherent light source. Using this basic principle a number of devices can be designed, few of these such as optical sensors, all-optical switches, optical add-drop multiplexer and modulator are discussed in this paper.

“…So there has been some important application for the all-fiber interleaver in fiber-optical communication and fiber-sensing systems. 2,3 In an all-fiber form, a singlestage MZI can be formed by joining two 2 × 2 fiber couplers as the basic structure for all-fiber interleavers. To meet the required characteristics of an interleaver, a lot of efficient MZI configurations have been proposed for achieving satisfactory filtering performance, by concatenating three or more fiber couplers, or different fiber couplers, such as all-fiber interleavers using many 2 × 2 fiber couplers, 4,5 all-fiber interleavers cascading three 3 × 3 fiber couplers, [6][7][8] and all-fiber interleavers consisting of 2 × 2 fiber coupler and 3 × 3 fiber coupler.…”

An interleaver with three cascaded 3 × 3 single-mode fiber couplers and one 2 × 2 single-mode fiber coupler is presented. Under certain values of physical length differences of the interferometer arms, 3-dB passband in odd channels and in even channels of the interleaver can realize an asymmetric passband wavelength response. Through a mathematical algorithm, the optimum splitting ratios, which are the relationship among the splitting ratios of the four couplers, were determined to achieve a flattop response within the passband for the interleaver. Based on the optimum splitting ratios, the output spectrums of the interleaver were analyzed and discussed. The results indicate that the amplitude of ripples in the "flat" region of the flattop passband wavelength response in odd channels and even channels are almost zero, the interleaver can achieve a perfect smoothing flattop response and good uniform channel passband, and the tolerance characteristics of the splitting ratios is favorable. In fabrication recipe, splitting ratios of the four couplers in the interleaver can be accurately controlled, so the degree of manufacturing difficulty is reduced.

“…The former usually contains several optical devices, such as FGC based on Mach-Zehnder interferometer [2,3] , in which other included device is composed of circulator and FBG. The individual devices included usually have stable performance and are commercial; however, the main disadvantages are high-insertion loss and high-cost.…”

This paper presents comprehensive research on fused-tapered Bragg reflection integrative FGC where high-quality and easy-fabricating are two main considerations. The technical procedure of FGC fabrication is fixed after a series of experiments. The possible factors that may determine the device performance were carefully analyzed. The fused-tapered FGC was successfully fabricated and a novel testing system was established. The adding and dropping functions of FGC were investigated experimentally.
