Abstract

Highly sensitive infrared photodetectors are needed in numerous sensing and imaging applications. In this paper, we report strong light-matter interaction at a quantum dot (QD) scale and the induced significant enhancement in photosensitivity and quantum efficiency. A plasmonic perfect absorber (PPA) cavity is fabricated with embedded quantum dots. The PPA cavity is designed to resonate with the intersubband transitions in quantum dots. The E-field overlaps with the QDs plus the energy resonance induce the strong light-matter interactions. Detailed analysis and experimental results will be presented.
