摘要:

相位调制器是光学中常用的器件。自由空间相位调制器通常由具有泡克尔斯效应的光学各向异性晶体构成。为了在光通过晶体时保持其偏振态,必须使光的偏振方向和入射角与晶体对准。在本研究中,我们证明了利用声光方法构建自由空间谐振相位调制器的可行性,该调制器具有宽接收角和对光偏振态的最小依赖性。这些调制器工作在兆赫兹频率范围,所需功率适中,孔径尺寸超过一平方厘米,厚度为亚毫米级。

英文摘要:

Phase modulators are commonly used devices in optics. Free-space phase modulators are typically constructed from optically anisotropic crystals exhibiting the Pockels effect. To preserve the light's polarization state as it propagates through the crystal, it is essential to align the polarization and angle of incidence of the light with respect to the crystal. In this study, we demonstrate the feasibility of constructing free-space resonant phase modulators with a broad acceptance angle and minimal dependence on the polarization state of light using an acousto-optic approach. These modulators operate in the megahertz frequency range, require modest power levels, have aperture sizes exceeding one square centimeter, and feature sub-millimeter thickness.
