Abstract

The magneto-optical microwave spectrum analyzer of sequential type based on waveguide- light interaction with magnetostatic surface wave (MSSW) in a planar yttrium-ion-garnet (YIG) film is suggested and investigated. The analyzer output response is proportional to the efficiency of dynamic TM-TE mode conversion induced by MSSW while sweeping of the frequency is carried out by tuning of the magnetic field strength. The increase of dynamic mode conversion efficiency of up to 35% per 1 W of input microwave power and narrowing of the interaction bandwidth of up to 4 MHz have been obtained by using a nonuniform magnetizing of the ferrite film. The analyzer has the following parameters: total overview frequency band 3.6 - 9.5 GHz, frequency resolution better than 10 MHz, sweeping time less than 0.5 s, and dynamic range of about 36 dB.
