Study on Insertion Loss of Fiber Fabry-Perot Filters
Fiber Fabry-Perot (FFP) filters have been widely used in optical fiber communications, and insertion loss (IL) is one of its important characteristics. Based on theoretically analysis, factors related to IL were discussed. In order to investigate the IL of different structures, simulations are carried out with finite-difference time-domain (FDTD) algorithm. Comparisons are made between the opti...
متن کاملDouble-Cavity Fabry-Perot Filters
Fabry-Perot Filters are major candidates for use as demultiplexers in wavelength division multiple access networks. In this paper we investigate the crosstalk limitations of such filters, compare their performances, and optimize the filter design to minimize the crosstalk degradation. 1 Bol.h witli the al)()rt;l.orlo for informltaiou a.icl I)ecision Ssleties. ilT.

متن کاملMicromachined Fabry-Perot Optical Filters
The design, fabrication and measured characteristics of micromachined FabryPerot (F-P) optical filters for the visible spectral range are presented. Silver films of 40-50 nm thickness, evaporated on a 300 nm thick low-stress silicon nitride membrane, are used as high-quality mirrors. Two parallel mirrors, with a square aperture of up to 2x2 mm and initial cavity gap of 1.2 μm, form a tunable Fa...
متن کاملFabry-Perot filters used for optical preprocessing.
A Fabry-Perot etalon placed in the object plane of a coherent optical processing system can be used as a variable bandpass preprocessing filter. Use of this filter leads to improved correlation signals in a matched spatial filter system. Experimental results are shown and compared with results obtained by two other preprocessing methods.
متن کاملExtrinsic Fabry-Perot interferometer fiber-optic microphone
In this paper we describe a new fiber-optic microphone developed as a passive acoustic sensor for traffic monitoring and vehicle classification. It is based on a fiber-optic extrinsic Fabry–Perot (FP) microinterferometer coupled to an external membrane for modulating the FP cavity length and a low coherent superluminescent diode as light source. The frequency characteristic as compared with a s...
