Abstract

Low power, narrowband integrated acousto-optic TE-TM mode convertors for the 0.8 mu m optical wavelength range have been developed. Acoustic drive power of less than 10 mW was required for 96% conversion efficiency. The 0.32 nm optical bandwidth corresponding to the acoustic bandwidth of 138 kHz achieved is the narrowest reported to date for a TE-TM mode convertor.
