High-resolution spectroscopy capable of resolving spectral features spaced by less than ~10pm is in particular extremely useful for characterizing the spectral properties of solid state quantum emitters, such as self-assembled quantum dots, and semiconductor micro-cavities and photonic-crystal nano-cavities with high Q-factors[3][4].
High-Sensitivity, High-Resolution Miniaturized Spectrometers for ...
2024年11月26日 · In this paper, we present a novel integration of GMRF devices with CMOS technology to develop a miniaturized spectrometer. This integration enhances the spectrometer’s sensitivity and resolution capabilities by employing a sophisticated mathematical algorithm that interprets coded spectral data derived from the GMRFs.
