The overall goal of photonics research is to understand and control light in new and richer
ways to facilitate new and richer applications. Many major developments to this end have …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Our ability to generate new distributions of light has been remarkably enhanced in recent
years. At the most fundamental level, these light patterns are obtained by ingeniously …

Photonic orbital angular momentum (OAM) carried by phase-structured vortex light is an
important and promising resource for the ever-increasing demand towards high-capacity …

Recently, full Poincaré beams (FPBs) with spatially variant polarization states spanning the
entire surface of the Poincaré sphere have attracted considerable interests. Expanding the …

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 show that a III-V semiconductor vertical external-cavity surface-emitting laser (VECSEL)
can be engineered to generate light with a customizable spatiotemporal structure. Temporal …

Structured light fields carrying orbital angular momentum (OAM) have been widely studied,
and a variety of applications have been found. The exploration of the generation of the …
