3D Printed Optics Achieves Broadband Structured Light

open access: yesAdvanced Optical Materials, EarlyView.
The arbitrary creation of structured light often requires complex design and fabrication steps and is largely limited to single wavelength. By leveraging off the toolkit for digital holograms, how complex amplitude modulation can be implemented as 3D printed optics in a manner that is broadband is shown, for the creation of multiwavelength forms ...

The Role of Theoretical Calculations for INVEST Systems: Complementarity Between Theory and Experiments and Rationalization of the Results

open access: yesAdvanced Optical Materials, EarlyView.
Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...

Dynamic Excitonic Beam Switching with Atomically‐Thin Binary Blazed Gratings

open access: yesAdvanced Optical Materials, EarlyView.
Two mirrored and interleaved blazed gratings are patterned into a monolayer WS2, contacted with gold electrodes inside an electrochemical cell. Applying a gate voltage to one of the grating electrode suppresses the exciton in that grating, enabling selective beam switching between diffractive orders.
