摘要

通过应用HeNe (632 nm波长)激光照明器件，报告了电驱动热压阻自维持振荡器的频率调谐和开/关控制能力。载流子的光激发被认为是控制压阻系数和电阻率的物理机制。这一结果具有重要意义，因为它们提供了一种通过光子学直接控制射频振荡器电子输出的新方法。

Optical control and tuning of thermal-piezoresistive self-sustained oscillators

The ability to frequency tune and provide on/off control of electrically driven thermal-piezoresistive self-sustained oscillators through the application of HeNe (632 nm wavelength) laser illumination to devices is reported in this work. Photoexcitation of charge carriers is presented as the physical mechanism to control the piezoresistive coefficient and electrical resistivity enabling these abilities. The results are significant in that they offer a novel means to directly control the electronic output of RF oscillators through photonics.
