Structured light is derived from the ability to tailor light, usually referring to the spatial control
of its amplitude, phase, and polarization. Although a venerable topic that dates back to the …

Modal decomposition of light has been known for a long time, applied mostly to pattern
recognition. With the commercialization of liquid-crystal devices, digital holography as an …

Mode division multiplexing (MDM) is mooted as a technology to address future bandwidth
issues and has been successfully demonstrated in free space using spatial modes with …

Spatial light modulators, as dynamic flat-panel optical devices, have witnessed rapid
development over the past two decades, concomitant with the advancements in micro-and …

Existing for almost four decades, liquid crystal on Silicon (LCOS) technology is rapidly
growing into photonic applications. We review the basics of the technology, from the wafer to …

Spatial light modulators (SLMs) are popular tools for generating structured light fields and
have fostered numerous applications in optics and photonics. Here, we explore the limits of …

Complex vector light modes with a spatial variant polarization distribution have become
topical of late, enabling the development of novel applications in numerous research fields …

The raw coronagraphic performance of current high-contrast imaging instruments is limited
by the presence of a quasi-static speckle (QSS) background, resulting from instrumental Non …

Caustics are responsible for a wide range of natural phenomena, from rainbows and
mirages to sparkling seas. Here, we present caustics in space-time wavepackets, a class of …

Through dedicated measurements in the optical regime we demonstrate that ptychography
can be applied to reconstruct complex-valued object functions that vary with time from a …
