Plasmonic has demonstrated the ability to enhance performances of photodetectors at a resonant wavelength. Absorption in a photodetector can reach 100% using nanophotonic plasmonic array. Plasmonic devices are confining light at the interface metal/dielectric, as a consequence, detection volume is smaller (100 to 1000 times) than in usual ...

Applied Physics Letters, 1976
A new class of infrared detectors is proposed and experimental results are presented for a prototype device. The material used is LaF3, an ionic conductor with a capacitance that varies exponentially with temperature. The detectivity of a prototype detector is estimated from measured signal voltages and incident power, and a Johnson noise voltage is ...

Infrared Detector For Mid-Infrared Astronomy
Astrophysics and Space Science, 1989Recent developments of infrared detectors and arrays for mid-infrared astronomical observations are discussed with an emphasis on technical issues in designing and fabricating photometers and cameras. The discussion includes a small-scale silicon bolometer array being tested at the Steward Observatory.

Infrared Spectra of Infrared Detectors
Spectroscopy Letters, 1984Abstract Thermal detectors of infrared (IR) radiation are generally covered with a highly absorbing “black” coating in order to assure that the incident radiation is absorbed.1–3 Essentially, the black material is the prime radiation sensor which becomes warmed by the photothermal effect and in turn warms a secondary sensor or “detector.” There have ...

Arrays of detectors sensitive to infrared radiation will enable astronomical observations to be made with shorter observing times than with discrete detectors and with good relative spatial accuracy. Systems using such arrays are being developed for astronomy in several regions of the electromagnetic spectrum.

Infrared Detector Refrigerators
1961Recent developments in semiconductor physics have produced infrared detector materials with increased detectivity out to the 40 μ wavelength region of the electromagnetic spectrum, In order to realize maximum sensitivity to wavelengths above approximately 6 μ, it is necessary to cool the detecting elements to temperatures ranging from 4° to 200°K.

Nanoantenna Infrared Detectors
2009This project focuses on devices that can be used for detection of thermal or long-wave infrared radiation, which is a frequency range for which developing detectors is of special interest. Objects near 300 K, such as humans and animals, emit radiation most strongly in this range, and absorption is relatively low in the LWIR atmospheric window between 8
