RF Filter Employing Optical Fiber Lattice Network and the Optimum Trapper
The radiation-frequency filters employing optical fiber lattice networks are investigated. The response functions of the fundamental elements are discussed. The optimum configuration conditions and parameter ranges of these lattices are deduced to achieve the optimum operation. A compensation method to realize a optimum notch filter is developed and implemented by matching the loss of fiber delay line with the coupling-coefficient of couplers. Experimental result shows that this method is effective, convenient, and well accorded with theory.
