Massive-parallel ultrafast random bit generation with a laser diode

Hui Cao

Yale University, United States of America

We demonstrate a new method for ultrafast generation of hundreds of random bit streams in parallel with a single laser diode. Spatio-temporal interference of many lasing modes in a specially designed cavity is introduced as a scheme for greatly accelerated random bit generation. Spontaneous emission noise makes the bit streams unpredictable. We achieve a total bit rate of 250 Tb/s, which is more than two orders of magnitude higher than the current record. Our approach is robust, compact, energy efficient, and should impact applications in secure communication and high-performance computation.

Does longitudinal light prevent Anderson Localization?

Bart van Tiggelen, Sergey Skipetrov

Universit ́e Grenoble Alpes, Centre National de la RechercheScientifique, France

Recent numerical simulations demonstrated the absence of an Anderson transition when light propagates in a dense medium of electric dipoles. We present a transport theory in which longitudinal waves induce a nouvel transport channel. the mixing of this channel with the usual transverse channel imposes a miniomum electromagnetic conductivity.

Nonlocal effective electromagnetic wave characteristics of composite media: beyond the quasistatic regime

Salvatore Torquato

Princeton University, United States of America

We derive exact nonlocal homogenized constitutive relations for the effective electromagnetic wave properties of disordered two-phase composites and metamaterials from first principles

[PRX, 11, 021002 (2021)]. This nonlocal formalism enables us to derive strong expansions for the effective dynamic dielectric constant that exactly account for multiple scattering from the long- to intermediate-wavelength regimes. We obtain accurate closed-form formulas for the dielectric response that incorporate crucial microstructural information. Exotic disordered hyperuniform media are shown to have novel wave characteristics. Thus, our findings can accelerate the discovery of novel electromagnetic composites.
