Abstract
Ultrabroadband terahertz (THz) optoelectronics has evolved into a powerful tool in femtosecond science and technology [1,2]. Field-sensitive detection of few-cycle THz transients with a constant carrier envelope phase, center frequencies of up to 41 THz, and spectral wings approaching the near infrared has been demonstrated [3]. Nevertheless, the complexity of the required laser systems limits their operation to specialized laboratories. In addition, novel applications in field-sensitive trace gas detection or all-optical phase control of near-infrared pulses call for still higher center frequencies [4].
