Plasmonics for On-Chip Photodetectors and Light Sources
… layer, act as a photodetector. Metallic metasurfaces have previously been considered less than ideal for polarization sensing, where they are usually operated in a reflection mode and require an external detector. Arrays of subwavelength plasmonic cavities, comprising a metasurface, are …

Ultra-sensitive Mid-infrared Detection Using Phononic Crystal Resonator-based Oscillator
Mid-infrared (MIR) detection is essential for many applications such as chemical sensing, communications, space explorations, and national defense. Existing MIR detectors are typically categorized into two major classes: (1) semiconductor photodetectors, which offer high responsivity and fast …
