FOCUS ON: Terahertz technology
Photonic integration improves heterodyne photomixing terahertz sources
Single-package hybrid optical integration of two semiconductor laser chips with a high-resolution wavelength discriminator has been used to realize a tunable terahertz source with a large scanning bandwidth.
Calibration tool aids terahertz researchers
Accurate and reliable calibration of terahertz time-domain spectrometers--a "calibration suite"--is essential to spectroscopic investigations in the frequency range from 0.1 to 3 THz.
Quantum dots enable integrated terahertz imager
A sensitive and frequency tunable terahertz detector based on carbon nanotube quantum dots creates a near-field terahertz imaging system in which all components are integrated on one semiconductor chip.
Standard software optimizes terahertz imaging
Off-the-shelf software can indeed tackle the unusual requirements of terahertz imaging--and in the process of optimizing such systems, help push terahertz technology toward industrial application.
