An epsilon-near-zero-based nonlinear platform for ultrafast re-writable holography
M. Zahirul Alam, Robert Fickler, Yiyu Zhou +3
We re-examine real-time holography for all-optical structuring of light and optical computation using a contemporary material: a subwavelength-thick, spatially unstructured film of…

Modeling beam propagation in a moving nonlinear medium
Ryan Hogan, Giulia Marcucci, Akbar Safari +4
Fully describing light propagation in a rotating, anisotropic medium with thermal nonlinearity requires modeling the interplay between nonlinear refraction, birefringence, and the…
Photon Number Resolving Detection with a Single-Photon Detector and Adaptive Storage Loop
Nicholas M. Sullivan, Boris Braverman, Jeremy Upham +1
Photon number resolving (PNR) measurements are beneficial or even necessary for many applications in quantum optics. Unfortunately, PNR detectors are usually large, slow, expensive…
Strong Reverse Saturation and Fast-Light in Ruby
Akbar Safari, Cara Selvarajah, Jenine Evans +2
We observe a strong reverse saturation of absorption in ruby at a wavelength of 473 nm. With an intensity-modulated laser, we observe that the peaks of the pulses appear more than…
Fourier-Engineered Plasmonic Lattice Resonances

Resonances in optical systems are useful for many applications, such as frequency comb generation, optical filtering, and biosensing. However, many of these applications are diffic…
Flat Magic Window
Felix Hufnagel, Alessio D'Errico, Hugo Larocque +3
Magic windows (or mirrors) consist of optical devices with a surface deformation or thickness distribution devised in such a way to form a desired image. The associated image inten…
Cross-polarized surface lattice resonances in a rectangular lattice plasmonic metasurface

Comment on "Nonreciprocal cavities and the time-bandwidth limit"
Kosmas L. Tsakmakidis, Yun You, Tomasz Stefanski +1
In their paper in Optica 6, 104 (2019), Mann et al. claim that linear, time-invariant nonreciprocal structures cannot overcome the time-bandwidth limit, and do not exhibit an advan…
