High-throughput speckle spectrometers based on multifractal scattering media
Bhupesh Kumar, Yilin Zhu, Luca Dal Negro +1
We present compact integrated speckle spectrometers based on monofractal and multifractal scattering media in a silicon-on-insulator platform. Through both numerical and experiment…
