摘要：

A novel MZI structure was proposed by taking advantage of orthogonal signal processing technology (OSPT) and used for frequency detection. The proposed MZI was made up of a 4 x 4 coupler and a 2 x 2 coupler, and the signal processing was realized by a numerical oscilloscope. The theoretical and experimental results demonstrated that the proposed MZI structure could decrease the influence of input power vibration and the output profile was linearity and the measurement range was enlarged to more than 6 times as large as before. The achievement in this research could not only make up for the weakness of conventional MZI, but also extent the application ranges of interferometer. (C) 2015 Elsevier GmbH. All rights reserved.
