Advances in cost-effective integrated spectrometers

HIGHLIGHTS

• who: Ang Li from the (UNIVERSITY) have published the research: Advances in cost-effective integrated spectrometers, in the Journal: (JOURNAL)
• what: The authors focus on the NIR and Raman spectroscopy techniques that are applicable for chip-size integrated spectrometers and summarize their key spectroscopic performance metrics required for different application scenarios. The main research focus since then have been given to improve the spectrometer`s performance by optimizing the gratings, including using Bragg reflectors63,64 or photonics crystal reflectors65, coating grating with silver films66, Retro-reflecting V-shaped facets67. etc., as plotted in Fig 7c . . .
