Title: | AlGaAs Ambient Light Detectors With a Human-Eye Spectral Response | Authors: | Lin, Tzu-Chiang Ma, Ta-Chun Lin, Hao-Hsiung |
Keywords: | AlGaAs; Ambient light detector; Commission Internationale de l'Eclairage (CIE) photopic luminosity function | Issue Date: | 2008 | Journal Volume: | 20 | Journal Issue: | 16 | Start page/Pages: | 1429-1431 | Source: | IEEE Photonics Technology Letters | Abstract: | We report an AlGaAs ambient light detector with a spectral response matched to Commission Internationale de l'Eclairage (CIE) photopic luminosity function. The detector consists of an Al0.6 Ga0.4As PIN junction for main absorption, a two-step-four-section compositional grading structure centered in the junction for auxiliary absorption, and a built-in filtering structure on top of the PIN junction. The peak responsivity of the detector is 0.096 A/W at 558 nm, which corresponds to 164 pA/lux in photometric unit. The CIE defined spectral mismatch index f1′ of the detector is as low as 5.8%. © 2008 IEEE. |
