摘要:

光学相变材料在可调超颖表面、可重构光子电路和非冯·诺依曼计算等新兴应用领域具有广阔的应用前景。然而,这些材料通常需要高熔化温度和快速淬火速率,以在其结晶和非晶相之间可逆地切换,这对大规模集成是一个重大挑战。在这里,我们提出了一种实验技术,利用GST中的热光效应,使空间和时间的热测量两个常见的电热微加热器设计目前使用的相变社区。我们的方法显示出良好的协议之间的实验结果和数值模拟,并提供了一个非侵入性的方法,电可编程相变器件的快速表征。

英文摘要:

Optical phase-change materials are highly promising for emerging applications such as tunable metasurfaces, reconfigurable photonic circuits, and non-von Neumann computing. However, these materials typically require both high melting temperatures and fast quenching rates to reversibly switch between their crystalline and amorphous phases, a significant challenge for large-scale integration. Here, we present an experimental technique which leverages the thermo-optic effect in GST to enable both spatial and temporal thermal measurements of two common electro-thermal microheater designs currently used by the phase-change community. Our approach shows excellent agreement between experimental results and numerical simulations and provides a non-invasive method for rapid characterization of electrically programmable phase-change devices.
