| To produce lower-energy terahertz radiation the electron's fall needed to be divided into smaller steps. |
| His group also works on photonic crystals and on terahertz sources and sensors. |
| The terahertz spectrometer is based on photoconductive dipole antennas, which are gated by ultra short optical pulses. |
| The other applications, though, may have to wait until terahertz lasers can stand the heat at room temperature. |
| The key to the new receiver is an HEB, which suffers from only about one-tenth of the noise of the Schottky barrier receivers previously used to detect terahertz radiation. |
| The molecular composition will be determined using fluorescent and Raman emission under pulsed laser excitation or by probing in the far infrared, terahertz, wavelength range. |
