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

Optical chaos is vital for various applications such as private communication, encryption, anti-
interference sensing, and reinforcement learning. Chaotic microcombs have emerged as …

Chaotic semiconductor lasers have been widely investigated for generating unpredictable
random numbers, especially for lasers with external optical feedback. Nevertheless, chaotic …

Chaos in nonlinear dynamical systems is featured with irregular appearance and with high
sensitivity to initial conditions. Near-infrared light chaos based on semiconductor lasers has …

Fifty years after the invention of the laser diode, and forty years after the butterfly effect
signified the unpredictability of deterministic chaos, it is commonly believed that a laser …

How small can a laser be made? What characteristic properties must a device possess to
still be called a laser? How can one prove laser action in the limiting cases of single-emitter …

We propose a scheme to control cavity quantum electrodynamics in the single photon limit
by delayed feedback. In our approach a single emitter-cavity system, operating in the weak …

We demonstrate a broadband and wavelength-tunable chaotic laser by using a
monolithically integrated wavelength-tunable chaotic semiconductor laser subject to optical …

We describe an efficient approach to modeling cavity quantum electrodynamics (QED) with
a time-delayed coherent feedback using quantum trajectory simulations. An analytical set of …

A simple superbunching pseudothermal light source is introduced based on common
instruments such as laser, lenses, pinholes, and ground glasses. g (2)(0)= 3.66±0.02 is …
