Spectral mapping of polarization-correlated photon-pair sources using quantum-classical correspondence
Hung-Pin Chung, Pawan Kumar, Kai Wang +7
Direct spectral characterization of a quantum photon-pair source usually involves cumbersome, costly, and time-consuming detection issues. In this study, we experimentally characte…
Broadband holography-assisted coherent imaging -- towards attosecond imaging at the nanoscale
Wilhelm Eschen, Sici Wang, Chang Liu +7
In recent years nanoscale coherent imaging has emerged as an indispensable imaging modality allowing to surpass the resolution limit given by classical imaging optics. At the same…
A fully automated dual-tip scanning near-field optical microscope for localized optical excitation and detection in the visible and near-infrared
Najmeh Abbasirad, Jonas Berzins, Kenneth Kollin +4
Near-field optical microscopes with two independent tips for simultaneous excitation and detection can be essential tools for studying localized optical phenomena on the subwavelen…
Scalable functionalization of optical fibers using atomically thin semiconductors
Gia Quyet Ngo, Antony George, Robin Tristan Klaus Schock +14
Atomically thin transition metal dichalcogenides are highly promising for integrated optoelectronic and photonic systems due to their exciton-driven linear and nonlinear interactio…
Discrete dispersion scan setup for measuring few-cycle laser pulses in the mid-infrared
Nils C. Geib, Richard Hollinger, Elissa Haddad +6
In this work, we demonstrate a discrete dispersion scan scheme using a low number of flat windows to vary the dispersion of laser pulses in discrete steps. Monte Carlo simulations…
Color filter arrays based on dielectric metasurface elements
Jonas Berzins, Fabrizio Silvestri, Giampiero Gerini +3
Digital imaging has been steadily improving over the past decades and we are moving towards a wide use of multi- and hyperspectral cameras. A key component of such imaging systems…
