论文摘要
时间镜头已被认为是在各种应用中操纵超快光脉冲的关键组成部分，从超快光谱到光学量子系统的接口。但是，电彩时间镜头的现有分析模型不足以利用其潜力。在这里，我们引入了一种可调的正弦时间镜头的可调时间孔径模型，可以在不修改设备的情况下精确控制CHIRP速率。我们得出了最大相误差的封闭形式表达式，并证明了其对时间孔径的依赖性。我们通过与常规方法相比，通过实现高斯脉冲的光谱带宽压缩1.6倍来验证模型。我们的框架提供了一种实用的工具，用于设计有效的时间光学系统，从而使应用程序中的时间成像和光学信号处理等应用在经典和量子光学器件中受益，而对Spectro-Spormoral属性的精确控制至关重要。
Time lenses have been recognized as crucial components for manipulating ultrafast optical pulses in various applications, from ultrafast spectroscopy to interfacing of optical quantum systems. However, the existing analytical model for the electro-optic time lens underutilizes its potential. Here, we introduce a tunable time aperture model for sinusoidal time lenses, enabling precise control over the chirp rate without modifying the device. We derive a closed-form expression for the maximum phase error and demonstrate its dependence on the time aperture. We experimentally validate the model by achieving a 1.6-fold enhanced spectral bandwidth compression of Gaussian pulses compared to the conventional approach. Our framework offers a practical tool for designing efficient temporal optical systems, benefiting applications such as temporal imaging and optical signal processing in both classical and quantum optics, where precise control over spectro-temporal properties is crucial.
