集成声光可调滤波器（ＡＴＯＦ）作为实用光通信器件，显示了巨大的潜力。其显著优点为；宽带调谐、窄线宽、低驱动功率、高速连续电调谐、同时的多波长选择等。此外，声光可调滤波器在光通信以外的领域也有广泛应用。但要把其开发为成熟的商品，还需要解决许多问题，如要改善制作的敏感性，提高中心频率的稳定性，进一步降低驱动功率，解决偏振有关性等。 Integrated acousto-optic tunable filter (ATOF) shows great potential as a practical optical communication device. Its significant advantages are: broadband tuning, narrow linewidth, low drive power, high-speed continuous electrical tuning, simultaneous multi-wavelength selection and more. In addition, acousto-optic tunable filters are also widely used in fields other than optical communication. However, to develop it into a mature product, many problems need to be solved, such as improving the sensitivity of production, improving the stability of the center frequency, further reducing the driving power and resolving polarization-related issues.
