Traditional wave kinetics describes the slow evolution of systems with many degrees of
freedom to equilibrium via numerous weak non-linear interactions and fails for very …

Over the past decades extensive research has been carried out to study the lasing
characteristics of random media. Some unexpected phenomena of random lasing action …

Disordered photonic materials can diffuse and localize light through random multiple
scattering, offering opportunities to study mesoscopic phenomena, control light–matter …

Border regions between areas where physical problems involve very few bodies with well‐
described interactions or immensely many (amenable to statistical description) are prone to …

We present a unified approach to the theory of multimodal laser cavities including a variable
amount of structural disorder. A general mean-field theory is studied for waves in media with …

Mode locking, the self‐starting synchronous oscillation of electromagnetic modes in a laser
cavity, is the primary way to generate ultrashort light pulses. In random lasers, without a …

Manipulating and controlling the optical energy flow inside random media is a research
frontier of photonics and the basis of novel laser designs. Here, we show that a metamaterial …

A many-mode laser with nonlinear modal interaction could serve as a model system to study
many-body physics. However, precise and continuous tuning of the interaction strength over …

We demonstrate an effective control of nonlinear interactions of lasing modes in a
semiconductor microdisk cavity by shaping the pump profile. A target mode is selected at the …

Plasmonic thin random lasers have many applications in photonic sensors and
communications. In this report, plasmonic thin random lasers were fabricated based on Au …
