    • An optoacoustic modulator contains first and second optoacoustic media, to which first and second piezoelectric vibrators are attached respectively. Herein, both of the first and second optoacoustic media are designed in same measurements, wherein they are arranged in series along an optical axis of a light signal in such a way that crystal orientation of the first optoacoustic media differs from crystal orientation of the second optoacoustic media with an angle of inclination of 90.degree.. In addition, the first piezoelectric vibrator is attached to a first surface of the first optoacoustic media which is placed in parallel with the optical axis of the light signal, while the second piezoelectric vibrator is attached to a second surface of the second optoacoustic media which is placed in parallel with the optical axis of the light signal, wherein the first surface is directed perpendicular to the second surface. The light signal, corresponding to incoming light incident on the optoacoustic modulator, is input to the first optoacoustic media. Then, the light signal transmitted through the first optoacoustic media is input to the second optoacoustic media, from which a desired output corresponding to outgoing light is output. The first and second piezoelectric vibrators are controlled by modulation signals, which are independently adjusted to cancel polarization mode dispersions of the optoacoustic media. In addition, it is possible to improve ripple characteristic of loss-wavelength dependency characteristic of the optoacoustic media, while it is possible to reduce an amount of crosstalk that occurs at a high-speed modulation mode.
    • 光声调制器包含第一和第二光声介质,分别附接有第一和第二压电振动器。 这里,第一和第二光声介质都被设计成相同的测量,其中它们沿着光信号的光轴被串联布置,使得第一光声介质的晶体取向不同于第二光声的晶体取向 介质倾角为90°。 此外,第一压电振动器附接到与光信号的光轴平行放置的第一光声媒体的第一表面,而第二压电振动器附接到第二光声媒体的第二表面,第二光声介质 与光信号的光轴平行放置,其中第一表面垂直于第二表面。 对应于入射到光声调制器上的入射光的光信号被输入到第一光声介质。 然后,通过第一光声介质传输的光信号被输入到第二光声介质,输出对应于出射光的期望输出。 第一和第二压电振动器由调制信号控制,调制信号被独立地调整以消除光声介质的偏振模色散。 此外,可以改善光声介质的损耗波长依赖特性的纹波特性,同时可以减少在高速调制模式下发生的串扰量。
