Abstract Random Lasers (RLs) and Random Fiber Lasers (RFLs) have been the subject of
intense research since their first experimental demonstration in 1994 and 2007, respectively …

Coherence phenomena arise from interference, or the addition, of wave-like amplitudes with
fixed phase differences. Although coherence has been shown to yield transformative ways …

Authentication is an essential cryptographic primitive that confirms the identity of parties
during communications. For security, it is important that these identities are complex, in order …

A laser is based on the electromagnetic modes of its resonator, which provides the feedback
required for oscillation. Enormous progress has been made toward controlling the …

This review attempts to compile the physics and chemistry of defects in zinc oxide (ZnO), at
both, the fundamental and application levels. The defects, either inherent ones or introduced …

Owing to their large absorption cross-sections and high photoluminescence quantum yields,
lead halide perovskite quantum dots (PQDs) are regarded as a promising candidate for …

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 …

Many imaging applications require increasingly bright illumination sources, motivating the
replacement of conventional thermal light sources with bright light-emitting diodes …

In the past ten years we have witnessed a revival of, and subsequent rapid expansion in, the
research on zinc oxide (ZnO) as a semiconductor. Being initially considered as a substrate …

The semiconductor ZnO has gained substantial interest in the research community in part
because of its large exciton binding energy (60 meV) which could lead to lasing action …
