Characterizing the orbital-angular-momentum (OAM) modes is critically important for OAM-
encoded data transfer. However, traditional characterizing approaches rely on either …

Multimode optical fibers support the dense, low-loss transmission of many spatial modes,
making them attractive for technologies such as communications and imaging. However …

Spatiotemporal optical wavepackets refer to light fields with sophisticated structures in both
space and time. The ability to produce such spatiotemporally structured optical wavepackets …

The optical coordinate transformation based on the ray model can flexibly and efficiently
complete the manipulation of complex light fields through a pair of phase plates, and is …

When light propagates through a complex medium, such as a multimode optical fiber (MMF),
the spatial information it carries is scrambled. In this work we experimentally demonstrate an …

Structured light can be encoded to carry information for free‐space optical communications
with an extended degree of freedom to increase the capacity, however, the accuracy issue …

Controlling wave transmission is crucial for various applications. In this work we apply the
concept of unitary control to manipulate multiport wave transmission. Unitary control aims to …

Over the last two decades, spatial light modulators (SLMs) have revolutionized our ability to
shape optical fields. They grant independent dynamic control over thousands of degrees-of …
