Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a silicon single-shot spectrometer with 0.008mm2 footprint, the smallest on CMOS compatible platforms. Experimental results confirm a bandwidth of 180nm with a resolution of 0.45nm. It opens new pathway towards commercial integrated spectrometers.
