Low-frequency noise properties of p-type GaAs/AlGaAs heterojunction detectors

Autor: Wolde, S, Lao, YF, Pitigala, PKDDP, Perera, AGU, Li, L, Khanna, SP, Linfield, EH

We have measured and analyzed, at different temperatures and bias voltages, the dark noise spectra of GaAs/AlGaAs heterojunction infrared photodetectors, where a highly doped GaAs emitter is sandwiched between two AlGaAs barriers. The noise and gain

Terahertz Radar Cross Section Characterization using Laser Feedback Interferometry with a Quantum Cascade Laser

Autor: Lui, HS, Taimre, T, Bertling, K, Lim, YL, Dean, P, Khanna, SP, Lachab, M, Valavanis, A, Indjin, D, Linfield, EH, Davies, AG, Rakic, AD

Radar cross section (RCS) measurements of complex, large objects are usually performed on scale models so that the measurement is carried out in a well-controlled environment. This letter explores the feasibility of RCS measurement using a terahertz

Terahertz imaging using quantum cascade lasers — a review of systems and applications

Autor: Dean, P, Valavanis, A, Keeley, J, Bertling, K, Lim, YL, Alhathlool, R, Burnett, AD, Li, LI, Khanna, SP, Indjin, D, Taimre, T, Rakić, AD, Linfield, EH, Davies, AG

The terahertz (THz) frequency quantum cascade laser (QCL) is a compact source of THz radiation offering high power, high spectral purity and moderate tunability. As such, these sources are particularly suited to the application of THz frequency imagi

Three-section terahertz quantum cascade lasers with externally biased photonic lattices

Autor: Kundu, I, Dean, P, Li, LH, Valavanis, A, Khanna, SP, Evans, CA, Cunningham, JE, Linfield, EH, Davies, AG

Publikováno v: MPNS COST Action Training School – MP1204 TERA-MIR Radiation: Materials, Generation, Detection and Applications

Single-mode (SM) operation of terahertz (THz)-frequency quantum cascade lasers (QCLs) is essential for gas sensing and for their use as local oscillators. Whilst such SM operation has been demonstrated previously using distributed feedback gratings a
