Mid-infrared materials and devices on a Si platform for optical sensing
Science and Technology of Advanced Materials, 2014 In this article, we review our recent work on mid-infrared (mid-IR) photonic materials and devices fabricated on silicon for on-chip sensing applications. Pedestal waveguides based on silicon are demonstrated as broadband mid-IR sensors. Our low-loss mid-
