We present a multiple microrings channel integrated chip and develop a signal processing method that enables parallel sensing with this chip. We utilize fast Fourier transform (FFT) and inverse fast Fourier transform (IFFT) to extract signals from different rings with different free spectra ranges (FSR). We verify this algorithm with temperature and solution sensing experiments. Compared with the conventional single-ring-single-resonance method, it shows improvements in up to 8 multi-channels capability and higher time resolution with the same experimental hardware.

单总线波导上多个微环的并行传感

我们提出了一种多微环通道集成芯片，并开发了一种信号处理方法，可以使用该芯片进行并行传感。我们利用快速傅里叶变换（FFT）和快速傅里叶逆变换（IFFT）来从具有不同自由光谱范围（FSR）的不同环中提取信号。我们通过温度和溶液传感实验验证了该算法。与传统的单环单谐振方法相比，在相同的实验硬件下，它显示出多达8个多通道能力的改进和更高的时间分辨率。
