Comparison of an InSb Detector and Upconversion Detector for Infrared Polarization Spectroscopy

Pedersen, Rasmus L. LU ; Hot, Dina LU and Li, Zongshan LU (2018) In Applied Spectroscopy 72(5). p.793-797
Abstract

This paper compares the signal-to-noise ratio obtained using an InSb photodiode for infrared (IR) polarization spectroscopy to that obtained using an upconversion detector, and shows a factor 64 improvement by the change. Upconversion detection is based on using sum frequency generation to move the IR optical signal to near-visible wavelengths to improve the sensitivity.
