Acoustic-optical device for optical filtering |
摘要 |
An acoustic-optical device for optical filtering includes two successive acoustic-optical interaction segments separated by an intermediate polarizer and each modifying the polarization of light guided by it. The modification depends on the frequencies of the interacting optical and acoustic waves. The acoustic waves are supplied symmetrically to the two interaction segments from a common electro-optical transducer. The transmission spectrum of the optical filter is subject to apodization by coupling between an auxiliary acoustic waveguide including the transducer and a main acoustic waveguide including the optical waveguide. Applications of the device include fiber optic telecommunication systems.
