Title

Mesa structured photoconductive antennas for 1.5 µm: All-fibre THz-TDS spectroscopy beyond 4 THz

Abstract
Photoconductive antennas (PCAs) based on InGaAs/InAlAs for operation at 1.5 m are improved by employing special structuring techniques, i.e. mesa etching. The detected THz amplitude is increased by a factor of over 27. The spectra show a significantly increased bandwidth exceeding 4 THz.
