Abstract :
An acoustic transducer for excitation of acoustic waves to an optical fibre with high efficiency and smooth frequency response is demonstrated. Reducing the size of the transducer to an order of the acoustic wavelength has resulted in low power consumption and smaller efficiency variations during wavelength tuning.
