  Title Probing superconducting gap dynamics with THz pulses Type Conference Article
  Year 2015 Publication CLEO Abbreviated Journal CLEO  
  Volume Issue Pages (up) SM3H.3 (1 to 2)  
  Keywords superconducting gap; electric fields; femtosecond pulses; near infrared radiation; picosecond pulses; superconductors; thin films  
  Abstract We studied superconducting gap dynamics in a BCS superconductor NbN and electron doped cuprate superconductor PCCO following excitation with near-infrared (NIR) and narrow band THz pulses. Systematic studies on PCCO imply very selective electron-phonon coupling.

  Title Quantum Dot Infrared Photodetectors: Photoresponse Enhancement Due to Potential Barriers Type Journal Article
  Year 2011 Publication Nanoscale Research Letters Abbreviated Journal Nanoscale res lett  
  Volume 6 Issue 1 Pages (up) 6  
  Keywords Quantum dots; Infrared detectors; Photoresponse; Doping; Potential barriers; Capture processes  
  Abstract Potential barriers around quantum dots (QDs) play a key role in kinetics of photoelectrons. These barriers are always created, when electrons from dopants outside QDs fill the dots. Potential barriers suppress the capture processes of photoelectrons and increase the photoresponse. To directly investigate the effect of potential barriers on photoelectron kinetics, we fabricated several QD structures with different positions of dopants and various levels of doping. The potential barriers as a function of doping and dopant positions have been determined using nextnano3 software. We experimentally investigated the photoresponse to IR radiation as a function of the radiation frequency and voltage bias. We also measured the dark current in these QD structures. Our investigations show that the photoresponse increases ~30 times as the height of potential barriers changes from 30 to 130 meV.

  Title Real-time GHz-rate counting of infrared photons using nanostructured NbN superconducting detectors Type Conference Article
  Year 2003 Publication CLEO/QELS Abbreviated Journal CLEO/QELS  
  Volume Issue Pages (up) CThM8  
  Keywords NbN SSPD; SNSPD; Infrared; Quantum detectors; Detectors; Photon counting; Quantum communications; Quantum cryptography; Single photon detectors; Superconductors  
  Abstract We demonstrate that our ultrathin, nanometer-width NbN superconducting single-photon detectors are capable of above 1-GHz-frequency, real-time counting of near-infrared photons. The measured system jitter of the detector is below 15 ps.

  Title Infrared heterodyne detection Type Conference Article
  Year 1968 Publication Proc. IEEE Abbreviated Journal  
  Volume 56 Issue 1 Pages (up) 37-46  
  Keywords minimum detectable power, quantum limit, infrared, IR mixer  
  Abstract Heterodyne experiments have been performed in the middle infrared region of the electromagnetic spectrum using the CO2laser as a radiation source. Theoretically optimum operation has been achieved at kHz heterodyne frequencies using photoconductive Ge:Cu detectors operated at 4°K, and at kHz and MHz frequencies using Pb1-xSnxSe photovoltaic detectors at 77°K. In accordance with the theory, the minimum detectable power observed is a factor of 2/η greater than the theoretically perfect quantum counter, hvΔf. The coefficient 2/η varies from 5 to 25 for the detectors investigated in this study. A comparison is made between photoconductive and photodiode detectors for heterodyne use in the infrared, and it is concluded that both are useful. Heterodyne detection at 10.6 µm is expected to be useful for communications applications, infrared radar, and heterodyne spectroscopy. It has particular significance because of the high radiation power available from the CO2laser, and because of the 8 to 14 µm atmospheric window.
