A compact Ge-rich graded-index SiGe platform with broadband low-loss propagation in the mid infrared

Not Accessible

Your library or personal account may give you access

Abstract

Ge-rich SiGe platforms with broadband and flat propagation loss of 2–3 dB/cm from λ = 5.5 µm to 8.5 µm are demonstrated. Such mid-IR integrated circuits are promising for many application including sensing or telecommunications.
