WF2.2 - NANO PHOTONIC STRUCTURES FOR SPECTRALLY-SELECTIVE ABSORPTION
Abstract
Abstract
We describe recent work using metallic nanophotonic structures to achieve spectrally-selective absorption. At UV wavelengths, we have designed, fabricated, and characterized spectrally-selective filters for silicon detectors based on aluminum plasmonic gratings. At infrared wavelengths, we have designed linewidth-tunable plasmonic gratings for absorption enhancement.
WF2.3 - ULTRA-SENSITIVE, FAST, AND ULTRA-LOW ENERGY NANO-PHOTODETECTORS INTEGRATED WITH SILICON CMOS
Abstract
Abstract
I will present our latest demonstration of nano-photodetectors, integrated on CMOS, with ~250 GHz gain-bandwidth product and ~30 photon sensitivity. These show excellent agreement with our unifying theory of sensitivity in low-dimensional photodetectors, and present a pathway for much higher performance including room-temperature single-photon detection.
