Fabry-Perot filters used for optical preprocessing.
نویسندگان
چکیده
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.

Novel tunable liquid crystal Fabry-Perot filters for Fiber-Optical system
Tunable filters with a wide tunable range that cover the whole C-band , or L-band, or both, have been found wide applications in fiber optical communication system, mainly in three domain: tunable laser, wavelength division multiplexing systems (WDM), and channel monitoring. Due to the growing demand in bit-rate and number of channels in WDM system, tunable narrow band pass filters are required...
متن کاملHighly Tunable Photonic Microwave Filter Based on a Broadband Optical Source Sliced by Two Cascaded Fabry-Perot Filters
In this paper we have proposed a highly tunable spectrum sliced photonic microwave band pass transversal filter for microwave and millimeterwave frequency applications. This filter configuration is based on two cascaded Fabry-Perot filters with different free spectral range and a broadband optical source. The high tunability of the filter is achieved by carefully choosing free spectral range of...
متن کاملNew Gaussian Approximation for Performance Evaluation of Optical Receivers with Arbitrary Optical and Electrical Filters
A new Gaussian approximation (GA) which takes into account the influence of arbitrary optical and electrical filters is proposed for the performance evaluation of optically preamplified receivers. Using the new GA, the receiver sensitivity is evaluated and notable performance differences were observed for several Fabry-Perot optical filters.
