Despite the extraordinary degree of interest in optical metamaterials in recent years, the
hoped-for devices and applications have, in large part, yet to emerge. It is becoming clear …

What do lotus flowers have in common with human bones, liquid crystals with colloidal
suspensions, and white beetles with the beautiful stones of the Taj Mahal? The answer is …

Q switching (QS) and mode locking (ML) are the two main techniques enabling generation
of ultrashort pulses. Here, we report the first observation of pulse evolution and dynamics in …

Mode-locked lasers have enabled some of the most precise measurements ever performed,
from attosecond time-domain spectroscopy to metrology with frequency combs. However …

The optics of correlated disordered media is a conceptually rich research topic emerging at
the interface between the physics of waves in complex media and nanophotonics. Inspired …

Mode-locking is a process in which different modes of an optical resonator establish stable
synchronization through non-linear interactions. This self-organization underlies light …

Organic–inorganic hybrid two-dimensional (2D) perovskites have recently attracted great
attention in optical and optoelectronic applications due to their inherent natural quantum …

The concept of random lasers exploiting multiple scattering of photons in an amplifying
disordered medium in order to generate coherent light without a traditional laser resonator …

Real-time spectroscopy based on an emerging time-stretch technique can map the spectral
information of optical waves into the time domain, opening several fascinating explorations …

For photonic devices, structural disorder and light scattering have long been considered
annoying and detrimental features that were best avoided or minimized. This review shows …
