All-fiber terahertz time-domain spectrometer operating at 1.5 microm telecom wavelengths.
The worldwide first all-fiber THz time-domain spectrometer for operation at 1.5 microm is presented. Applications up to 3 THz are demonstrated. Key devices are photoconductive antennas based on novel LT InGaAs/InAlAs multi-layer structures.
