To obtain a high extinction ratio and rapid response for a waveguide-type acoustooptic modulator (AOM), polarization control of the optical guided wave in a new configuration using a reverse-proton-exchange (RPE) LiNbO3 straight waveguide and a leaky surface acoustic wave (LSAW) which propagates perpendicular to the straight waveguide was proposed. For a sample with an LSAW wavelength of 136 $\mu$m, the maximum modulation efficiencies for optical wavelength of 633, 532, and 473nm were 87, 43, and 40%, respectively. For a sample with an LSAW wavelength of 20 $\mu$m, the response time of 22 ns was obtained and was almost equal to the time required for the propagation of the LSAW through he interdigital transducer width. |
