Abstract: We demonstrate an integrated all-fiber mid-infrared (mid-IR) supercontinuum (SC) source generated by a 1.95 μm master oscillator power amplifier (MOPA) system and a single mode ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) fiber. The maximum average output power is 10.67 W with spectral bandwidth covering from ~1.9 to 4.1 μm. The single mode ZBLAN fiber and silica fiber are thermal spliced to enhance the robustness and practicability of the system. It is, to the best of our knowledge, the first high power integrated compacted all-fiber mid-IR SC source based on thermal spliced silica fiber and ZBLAN fiber.

Abstract: Photoconductive switches were the key components that allowed thegeneration and detection of coherent broadband electromagneticpulses at terahertz frequencies, opening the possibility ofperforming spectroscopy and, therefore, measuring complex dielectricproperties of materials in this band which was mostly unexplored. Inthis article we present a brief introduction to the operationprinciples of these devices. Subsequently we present a review of thecurrent state-of-the-art in these this field and discuss thechallenges to be faced in future development of these devices.
