Large-scale networks of phase synchronization are considered to regulate the communication between brain regions fundamental to cognitive function, but the mapping to their structural substrates, i.e., the structure-function relationship, remains poo

We introduce a CW two-color Ti:sapphire laser for terahertz spectroscopic applications. The laser provides two parallel beams at independently tunable wavelengths allowing one to select a difference frequency in the range from below 20 GHz to 50 THz.

We report on fabrication and high-frequency performance of our photodetectors and photomixers based on freestanding low-temperature-grown GaAs (LT-GaAs). In our experiments, the LT-GaAs/AlAs bilayers were grown on 2-inch diameter, semi-insulating GaA

Optical heterodyne millimeter-wave (mm-wave) generation using traveling-wave photodetectors (TW-PDs) is examined both experimentally and theoretically. Ultrahigh-frequency (110 GHz, 160 GHz and 460 GHz) InP-based 1.55 /spl mu/m TW-PDs were fabricated

Summary form only given. Heterodyne downconversion, or photomixing, of two CW laser beams has proven to be a successful way to generate narrow-band radiation in the terahertz spectral region. For the first demonstration of efficient and frequency-tun
