Random lasers (RLs) are a particular class of optical devices. In a random laser, the optical
feedback is provided by scattering media rather than by an optical cavity, as for traditional …

A disordered photonic medium is one in which scatterers are distributed randomly. Light
entering such media experiences multiple scattering events, resulting in a “random walk” …

The possibility to produce laser action involving biomaterials, in particular (single) biological
cells, has fostered the development of cellular lasers as a novel approach in biophotonics. In …

Recently, wearable sensor technology has drawn attention to many health-related
appliances due to its varied existing optical, electrical, and mechanical applications …

Over the past few decades, optoelectronic devices have played a key role in human life and
modern technology. To meet the development trends of the industry, photonics with tunable …

Microlasers based on biomaterials have attracted enormous interest because of their
promising potential for future applications in medical treatments, bio-tracking, and …

The miniaturization of random lasers to the micrometer scale is challenging but fundamental
for the integration of lasers with photonic integrated circuits and biological tissues. Herein, it …

Here we reported on a tunable and stable random laser based on the abalone shell. The
groove structure on the inner surface of abalone shell can support coherent random lasing …

Recently, the ineffectiveness of conventional antibiotic treatments against multidrug-resistant
bacteria stimulated the development of novel effective disinfection technologies. Ultraviolet …

In this study, we demonstrate a simple approach to fabricate a high-performance random
laser (RL) from the natural inverse photonic glass structure of Artemia eggshells. Herein, the …
