Analysis and design of F-P cavity resonator filters with LiNbO3 optical waveguides

With the transfer matrix method,the transmission coefficient of a F-P cavity filter with a LiNbO3 optical waveguide is reasoned out.By computer simulation,the effects of structure parameters of the F-P cavity filter on the transmission light intensity,bandwidth and finess are analyzed.The results show that the transmission light intensity becomes weaker and bandwidth becomes wider with the increasing of propagation loss,and that with the increasing of reflectivity,the transmission light intensity becomes weaker and the bandwidth becomes narrower,however the finess becomes increscent.The optimizing parameters of the F-P cavity filter are given by considering the transmission light intensity and finess.
