Examining the physical properties of materials - particularly of toxic liquids - under a wide range of thermodynamic states is a challenging problem due to the extreme conditions the material has to be exposed to. Such temperature and pressure regime

We present Brillouin-Mandelstam measurements of hard-to-reach, thermodynamic regimes in fully-sealed, CS2-filled liquid-core optical fibers. We investigate the Brillouin response in the positive and negative pressure regimes for isochoric and isobari

Liquid-core fibers are a versatile platform for nonlinear light-matter interactions, combining highly nonlinear materials like carbon disulfide (CS 2 ) or nitrobenzene with the confinement and long interaction length of optical fibers. While there is

Optical fibers with a liquid core provide a versatile platform for nonlinear optics [1] . Filled with carbon disulfide (CS 2 ), the high linear refractive index of 1.59 at 1549 nm and low speed of sound of 1250 ms −1 , compared to silica, ensures g

We investigate the frequency-resolved intensity noise spectrum of an Yb-doped fiber amplifier down to the fundamental limit of quantum noise. We focus on the kHz and low MHz frequency regime with special interest in the region between 1 and 10 kHz. I

We investigate experimentally and theoretically the polarization switching found in single-transverse-mode vertical-cavity surface-emitting lasers (VCSELs) when subject to parallel optical injection. Our analysis focuses on a recently observed state
