ETpathfinder: a cryogenic testbed for interferometric gravitational-wave detectors
A. Utina, A. Amato, J. Arends +112
The third-generation of gravitational wave observatories, such as the Einstein Telescope (ET) and Cosmic Explorer (CE), aim for an improvement in sensitivity of at least a factor o…
Freeform imaging system design with multiple reflection surfaces
Yunfeng Nie, David R. Shafer, Heidi Ottevaere +2
Reflective imaging systems form an important part of photonic devices such as spectrometers, telescopes, augmented and virtual reality headsets or lithography platforms. Reflective…
Freeform imaging systems: Fermat's principle unlocks 'first time right' design
Fabian Duerr, Hugo Thienpont
For more than 150 years, scientists have advanced aberration theory to describe, analyse, and eliminate imperfections that disturb the imaging quality of optical components and sys…
Predicting graphene's nonlinear-optical refractive response for propagating pulses
David Castello-Lurbe, Hugo Thienpont, Nathalie Vermeulen
Nonlinear-optical refraction is typically described by means of perturbation theory near the material's equilibrium state. Graphene, however, can easily move far away from its equi…
Negative Kerr nonlinearity of graphene as seen via chirped-pulse-pumped self-phase modulation
Nathalie Vermeulen, David Castello-Lurbe, JinLuo Cheng +6
We experimentally demonstrate a negative Kerr nonlinearity for quasi-undoped graphene. Hereto, we introduce the method of chirped-pulse-pumped self-phase modulation and apply it to…
Deterministic polarization chaos from a laser diode
Martin Virte, Krassimir Panajotov, Hugo Thienpont +1
Fifty years after the invention of the laser diode and fourty years after the report of the butterfly effect - i.e. the unpredictability of deterministic chaos, it is said that a l…
Quantum filtering using POVM measurements
Ram A. Somaraju, Alain Sarlette, Hugo Thienpont
The objective of this work is to develop a recursive, discrete time quantum filtering equation for a system that interacts with a probe, on which measurements are performed accordi…
