Abstract: A novel on-chip spectrometer device using combined functionalities of a micro-ring resonator and a planar diffraction grating is proposed and demonstrated. The spectrometer has a 2 mm 2 ...

Abstract: The single-detector spectrometers based on 2D layer van der Waals (vdW) heterojunctions offer advantages in spectral reconstruction due to their high sensitivity, tunable optical properties, ...

Materials science is an interdisciplinary field concerned with the understanding and application of the properties of matter. Materials scientists study the connections between the underlying ...

The mini-spectrometer TF series is a polychromator provided in a compact, thin case that houses optical elements, image sensor, and driver circuit. Spectrum data can be acquired by guiding measurement ...
