چکیده
We demonstrate an automatic tunable transversal notch filter based on uniform fiber Bragg gratings and a broadband optical source. High tunability can be performed by stretching the fiber with the gratings written in series. Also, high sidelobe supression can be achieved by introducing tunable attenuators in a parallel configuration of the gratings.

Tunable all-optical negative multitap microwave filters based on uniform fiber Bragg gratings.
We present a novel and simple technique for obtaining transversal filters with negative coefficients by using uniform fiber Bragg gratings. We demonstrate a wide tuning range, good performance, low cost, and easy implementation of multitap filters in an all-optical passive configuration in which negative taps are obtained by use of the transmission of a broadband source through uniform Bragg gr...
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 کاملFlexible Tunable Spectrum Sliced Microwave Photonic Filter Using Parallel Fabry-Pérot Filters and Fiber Bragg Grating
A simple and low-cost spectrum sliced microwave photonic filter with high tunability has been implemented. This is based on use of two Fabry-Pérot filters with same free spectral range connected in parallel but one filter with an external fiber delay. An extension of this configuration with Fiber Bragg Grating (FBG) as delay element is also demonstrated. This architecture overcomes the tuning d...
متن کاملExperimental investigation of wavelength-tunable WADM and OXC devices using strain-tunable fiber Bragg gratings
Ž . Ž . Two reconfigurable wavelength addrdrop multiplexer WADM and optical cross-connect OXC devices based on Ž . strain-tunable fiber Bragg gratings ST-FBGs are proposed. The feasibility of WADM is verified by measuring the Ž . Ž . bit-error-rate performance of the dropped cross-connect and pass-through no cross-connect channels over a 50and 100-km standard single-mode fiber for a 2.5 Gbrs sy...
متن کاملTunable and reconfigurable multi-tap microwave photonic filter based on dynamic Brillouin gratings in fibers.
We propose and experimentally demonstrate new architectures to realize multi-tap microwave photonic filters, based on the generation of a single or multiple dynamic Brillouin gratings in polarization maintaining fibers. The spectral range and selectivity of the proposed periodic filters is extensively tunable, simply by reconfiguring the positions and the number of dynamic gratings along the fi...
