我们在绝缘体上硅(SOI)平台上实验演示了一种基于迈克尔逊干涉仪(MIS)空间外差阵列的紧凑型傅里叶变换片上光谱仪。与马赫-曾德尔干涉仪(MZI)(δλ=1.6 nm)相比，在空间外差列阵干涉仪臂之间具有相同的渐进几何光程差的情况下，光相位延迟增加了一倍，波长分辨率(δλ=0.8 nm)增加了一倍。我们的概念验证设备展示了一种解决片上FTIR固有的带宽分辨率折衷的方法，这对于需要紧凑型片内外形规格的个位数皮秒分辨率的光学传感应用具有重要意义。
We experimentally demonstrate a compact Fourier Transform on-chip spectrometer based on spatially heterodyned array of Michelson interferometers (MIs) in a silicon-on-insulator (SOI) platform. We demonstrate that with the same progressive geometric path length difference between the spatially heterodyned arrayed interferometer arms, MIs double the optical phase delays and thus double the wavelength resolution (δλ=0.8nm) compared to Mach-Zehnder interferometers (MZIs) (δλ=1.6nm). Our proof-of-concept device demonstrates one method to address the bandwidth-resolution tradeoff inherent in on-chip FTIRs, which gains in significance for optical sensing applications requiring single digit picometers resolution in compact on-chip form factors.
