Digital synthesis of optical interleaver based on a solid multi-mirror Fabry-Perot interferometer

摘要

Starting from the matrix method introduced by Stadt, Muller, and Bae, digital signal processing (DSP) techniques are used to design multi-mirror Fabry-Perot (MMFP) interferometers. Solid MMFP interleavers with different filter orders and duty cycles are synthesized and optimized with this DSP method to achieve high isolation, wide flattop, and large passband bandwidth ratio. Tolerance analysis of a typical structure is presented as well. This method is used to explain an interferometric measurement to show its utility in experimental practice. This method can also be applied to the design and analysis of other interference devices based on Fabry-Perot etalons. (C) 2017 Optical Society of America
