Abstract This Review Article provides an overview of chaos in laser diodes by surveying
experimental achievements in the area and explaining the theory behind the phenomenon …

Complex phenomena in photonics, in particular, dynamical properties of semiconductor
lasers due to delayed coupling, are reviewed. Although considered a nuisance for a long …

We numerically investigate reservoir computing based on the consistency of a
semiconductor laser subjected to optical feedback and injection. We introduce a chaos mask …

Generation of practical random numbers (RNs) by a spintronics-based, scalable truly RN
generator called" spin dice" was demonstrated. The generator utilizes the stochastic nature …

Traditionally, chaotic systems are built on the domain of infinite precision in mathematics.
However, the quantization is inevitable for any digital devices, which causes dynamical …

Random numbers are widely used for information security, cryptography, stochastic
modeling, and quantum simulations. Key technical challenges for physical random number …

We report a 12.5 Gb/s physical random number generator (RNG) that uses high-speed
threshold detection of the spectrally-sliced incoherent light produced by a fiber amplifier. The …

Optical chaos generated by perturbing semiconductor lasers has been viewed, over recent
decades, as an excellent entropy source for fast physical random bit generation (RBG) …

We experimentally demonstrate fast physical random bit generation from bandwidth-
enhanced chaos by using three-cascaded semiconductor lasers. The bandwidth-enhanced …
