Abstract

A fiber coupled terahertz time-domain spectroscopy (THz TDS) system which is driven by a pulsed monolithic semiconductor laser is presented. A bandwidth of over 0.6 THz with a signal to noise ratio (SNR) of 45 dB has been achieved at a wavelength of 1550 nm. This concept could pave the way towards ultra-compact and low-cost THz TDS systems.
