Removal of guided acoustic wave Brillouin scattering to the quantum-noise limit using symmetric interferometry in twisted photonic crystal fibers
Vishal Choudhury, Kevin Jaksch, Markus Lippl +3
Guided acoustic wave Brillouin scattering (GAWBS) is a major obstacle in fiber-based quantum and high-speed classical communication systems as well as in interferometry. The transv…

Broadband THz spectroscopy system beyond 25 THz using BNA crystals and a tunable single-ring-fiber compressor
Wei Cui, Aswin Vishnuradhan, Markus Lippl +4
We present a terahertz time-domain spectroscopy (THz-TDS) system which accesses a broadband spectrum, efficiently covering the so-called "new THz gap" between 5 and 15 THz and exte…
