Abstract
The TE⇄TM mode conversion by acoustic surface waves in a ZnO‐film optical waveguide fabricated on a fused‐quartz substrate is described. An efficient mode conversion as high as 88% has been accomplished in a waveguide with a film thickness of 5 μm at an acoustic frequency of 226 MHz and an acoustic power of 350 mW.Keywords
