In recent years, a push for developing novel silicon photonic devices for telecommunications has generated a vast knowledge base that is now being leveraged for developing sophisticated photonic sensors. Silicon photonic sensors seek to exploit the strong confinement of light in nano-waveguides to transduce changes in physical state to changes in resonance frequency. In the case of thermometry, the thermo-optic coefficient, i.e., changes in refractive index due to temperature, causes the resonant frequency of the photonic device such as a Bragg grating to drift with temperature. We are developing a suite of photonic devices that leverage recent advances in telecom compatible light sources to fabricate cost-effective photonic temperature sensors, which can be deployed in a wide variety of settings ranging from controlled laboratory conditions, to the noisy environment of a factory floor or a residence. In this manuscript, we detail our protocol for the fabrication and testing of photonic thermometers.
近年来,为开发用于电信的新型硅光子器件所做的努力已经积累了大量的知识基础,目前这些知识正被用于开发精密的光子传感器。硅光子传感器试图利用纳米波导中对光的强限制,将物理状态的变化转化为共振频率的变化。在温度测量中,热光系数,即由于温度导致的折射率变化,会使诸如布拉格光栅等光子器件的共振频率随温度漂移。我们正在开发一套光子器件,利用电信兼容光源的最新进展来制造具有成本效益的光子温度传感器,这些传感器可以部署在从受控实验室条件到工厂车间或住宅的嘈杂环境等各种环境中。在本手稿中,我们详细介绍了光子温度计的制造和测试协议。
