Multidimensional light-field control is opening new frontiers in photonics. Recent breakthroughs in metasurface design and the integration of Dammann optimisation with spin-decoupled phase modulation enable the simultaneous manipulation of phase, amplitude, polarisation, and orbital angular momentum to project information into three-dimensional space. This paradigm shift towards full-parameter control in stereoscopic volumes is promising for revolutionising applications from high-capacity optical communications to secure encryption and parallel computing, marking a significant advancement in integrated photonic systems.

A robust saturable absorber that integrates MoS2-BN-graphene-BN-MoS2 nanocavity on fibre is proposed and demonstrated. The proposed absorber lowers saturation intensity to 22 MW cm−2, raises polarisation tolerance to 85%, and stabilises single-soliton mode-locking in all-fibre lasers. This work provides a practical and high-performance solution for achieving stable mode-locking in all-fibre lasers, effectively overcoming the inherent limitations of conventional 2D saturable absorbers.

Recent advances have highlighted new directions for vertical-cavity surface-emitting lasers (VCSELs). Engineering the device architecture enabled electrically pumped surface-emitting amplified spontaneous emission from colloidal quantum dots, while non-circular cavity geometries enhanced power scaling, coherence control, and polarization stability. These breakthroughs broaden VCSEL research, pointing to customizable, application-specific devices.

A direct photolithography approach using rigid crosslinkers was developed for the precise patterning of quantum dot (QD) layers, producing high-resolution RGB arrays with pixel sizes down to 1 μm. This strategy suppresses QD degradation typically associated with conventional high-UV photolithography while enhancing electron confinement within the QDs, thereby preserving their luminescent properties. As a result, high-performance patterned red QLEDs were successfully fabricated.
