A surface plasmon enhanced infrared photodetector based on InAs quantum dots.
In this paper, we report a successful realization and integration of a gold two-dimensional hole array (2DHA) structure with semiconductor InAs quantum dot (QD). We show experimentally that a… Expand

We design a polarization-sensitive resonator for use in mid-infrared photodetectors, utilizing a photonic crystal cavity and a single or double-metal plasmonic waveguide to achieve enhanced detector… Expand
Low-strain InAs∕InGaAs∕GaAs quantum dots-in-a-well infrared photodetector
The authors report the design, growth, fabrication, and characterization of a low-strain quantum dots-in-a-well (DWELL) infrared photodetector. This novel DWELL design minimizes the inclusion of the… Expand
Reduction in dark current using resonant tunneling barriers in quantum dots-in-a-well long wavelength infrared photodetector
We report the use of resonant tunneling (RT) assisted barriers to reduce the dark current in quantum dots-in-a-well (DWELL) infrared photodetectors. Designed RT barriers allow energy-selective… Expand

We report Quantum Dot Infrared Detectors (QDIP) where light coupling to the self assembled quantum dots is achieved through plasmons occurring at the metal-semiconductor interface. The detector… Expand
Investigation of multistack InAs/InGaAs/GaAs self-assembled quantum dots-in-double-well structures for infrared detectors
The authors report the InAs/InGaAs/GaAs/AlGaAs quantum dots-in-double-well (D-DWELL) design, which has a lower strain per DWELL stack than the InAs/InGaAs/GaAs DWELLs thereby enabling the growth of… Expand
Demonstration of Bias Controlled Algorithmic Tuning of Quantum Dots in a Well ( DWELL ) Mid-infrared Detectors
Experimental observation of anomalous thermal radiation from a three-dimensional metallic photonic crystal.
We report some striking results on thermal radiation properties of a resonantly coupled cavity photonic crystal (PhC) at elevated temperatures (T = 400-900 K). We experimentally found that at… Expand
Order-of-magnitude enhancement of intersubband photoresponse in a plasmonic quantum dot system.
The unprecedented ability of metallic subwavelength structures to confine and concentrate light into subwavelength spaces has led to new physics and exploration of novel devices. In this Letter, we… Expand
