Optimal configuration of the waveguide acousto-optic TE-TM polarization mode convertor on X-cut lithium niobate substrate

An excitation, distribution, and interaction of surface acoustic waves (SAW) with the guided light in integrated optical structures on X-cut lithium niobate substrates were studied. The resonance excitation frequencies, the spatial SAW distribution and the TE-TM optical mode conversion efficiency we...

Description
Summary:An excitation, distribution, and interaction of surface acoustic waves (SAW) with the guided light in integrated optical structures on X-cut lithium niobate substrates were studied. The resonance excitation frequencies, the spatial SAW distribution and the TE-TM optical mode conversion efficiency were investigated. An optimal configuration and most suited material of interdigital transducer (IDT) for integrated acousto-optic devices were found.
