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. |
