Today, a lot of attention is paid to remote controlled opto-electronic devices. Many of them are commonly used in the society, industry, and science. Accessories dedicated to the particular utilization are desired. The point is to find a simple way to obtain smart and functional appliances. Materials engineering faces such problems and provides a variety of solutions concerning advanced material design, preparation, and utilization. Photochromic materials represent one of the already known materials, which still find other objectives in new fields of life. In our work, we present two differently constructed photoresponsive polymers, which give significantly different nonlinear optical (NLO) response visible as noticeable optical signal modulation. By playing with diversified laser light energy or its frequency, NLO output characterized appealing, and individual characteristics (doubled Δ ∼0.02 vs 0.04 and entirely different kinetics for two similar materials and the same laser pumping). Interestingly, high output signal repeatability and stability were achieved, which indicate the investigated materials as promising candidates in the construction of various opto-electronic devices. Additionally, a set of photoresponsive studies, reflectometry, and theoretical insights was performed and included in this work.
如今，遥控光电器件备受关注。其中许多在社会、工业和科学领域都有广泛应用。人们期望有专门用于特定用途的配件。关键在于找到一种简单的方法来获得智能且实用的设备。材料工程面临此类问题，并针对先进材料的设计、制备和应用提供了多种解决方案。光致变色材料是已知材料之一，在新的生活领域中仍有其他用途。在我们的工作中，我们展示了两种结构不同的光响应聚合物，它们呈现出明显不同的非线性光学（NLO）响应，表现为显著的光信号调制。通过改变激光能量或其频率，NLO输出具有吸引人的独特特性（两种相似材料在相同激光泵浦下，倍频Δ分别约为0.02和0.04，且动力学完全不同）。有趣的是，实现了高输出信号重复性和稳定性，这表明所研究的材料有望用于构建各种光电器件。此外，还进行了一系列光响应研究、反射测量和理论分析，并纳入了本工作。
