Mach–Zehnder–Fano interferometer
We introduce a concept of the Mach–Zehnder–Fano interferometer by inserting a cavity exhibiting Fano resonance into a conventional interferometer. By employing the scattering-matrix approach, we demonstrate that the transmission becomes sensitive to a position of the cavity such that an asymmetric structure exhibits a series of narrow resonances with almost perfect reflection. We discuss how to...
متن کاملAsymmetrical in-fiber Mach-Zehnder interferometer for curvature measurement.
We demonstrated a compact and highly-sensitive curvature sensor based on a Mach-Zehnder interferometer created in a photonic crystal fiber. Such a Mach-Zehnder interferometer consisted of a peanut-like section and an abrupt taper achieved by use of an optimized electrical arc discharge technique, where only one dominating cladding mode was excited and interfered with the fundamental mode. The u...
متن کاملA Thermally Annealed Mach-Zehnder Interferometer for High Temperature Measurement
An in-fiber Mach-Zehnder interferometer (MZI) for high temperature measurement is proposed and experimentally demonstrated. The device is constructed of a piece of thin-core fiber (TCF) sandwiched between two short sections of multimode fiber (MMF), i.e., a MMF-TCF-MMF structure. A well-defined interference spectrum is obtained owing to the core-mismatch, and the interference dips are sensitive...
متن کاملPerformance Analysis of Mach-Zehnder Modulator Using Fuzzy Logic Generator
-In this paper, we analyze the impact of extinction ratio (Ron/off) of Mach-Zehnder (MZ) amplitude modulator using Fuzzy logic generator. The system performance has been analyzed by varying the value of extinction ratio (Ron/off) from 0 to 10 dB. It is found that the system gives optimum performance at extinction ratio value 9.965 dB. Further, the fuzzy model of the system is developed using AN...
متن کاملStrain Measurement in a Mach-Zehnder Fiber Interferometer using Data Dependent System Method
A fiber-optic strain measurement technique based on data dependent system (DDS) in Mach-Zehnderfiber interferometer is presented. The interferogram recorded from the interferometer has been digitized and characterized by means of an autoregressive model. The phase change due to the measurand has been obtained from the self-coherence function of the interferogram. It would provide the phase dist...
