Discrete Cavity Dynamics in Free-Space Brillouin Laser

Jiabao Peng, Longjie Zhang, Zhenxu Bai +2

Highly coherent lasers are central to modern photonics. To date, high-coherence operation has been achieved predominantly in microcavity and fiber-based platforms. More recently, f…

Simulating vacuum birefringence with a diffractive beam propagation code

Aimé Matheron, Michal Šmíd, Matt Zepf +1

Ninety years after their prediction, quantum vacuum nonlinearities in macroscopic electromagnetic fields still await a direct experimental verification in the laboratory. A particu…

Energy Time Ptychography for one-dimensional phase retrieval

Ankita Negi, Leon Merten Lohse, Sven Velten +9

Phase retrieval is at the heart of adaptive optics and modern high-resolution imaging. Without phase information, optical systems are limited to intensity-only measurements, hinder…

Towards direct nonlinear compression of energetic sub-nanosecond pulses to the ultrafast regime

Gaspard Beaufort, Nayla Jimenez, Gunnar Arisholm +5

Applications of terawatt-class lasers can enormously benefit from pulse trains with kHz repetition rates. The associated unprecedented combinations of peak and average powers requi…

Multi-wavelength ghost imaging: a review

Tong Tian, Sukyoon Oh, Christian Spielmann

Ghost imaging (GI) forms images from intensity-correlation data collected by a single-pixel detector, decoupling illumination and sensing. Since its quantum-photon origins, the tec…

Interferometric measurement of nuclear resonant phase shift with a nanoscale Young double waveguide

Leon M. Lohse, Ankita Negi, Markus Osterhoff +6

The phase shift of an electromagnetic wave, imprinted by its interaction with atomic scatterers, is a central quantity in optics and photonics. In particular, it encodes informatio…
