Simple electrically tunable liquid crystal spatial phase modulator

Zhanna Zemska et al.

Summary: We describe a simple electrically tunable liquid crystal element that can be controlled by 4 electrodes, capable of generating refractive index distributions corresponding to a standard spherical lens, axicon, cylindrical lens, and prism. The switching between different operation modes is done in a very simple electronic way. This element has significant potential for applications in adaptive imaging, optogenetics, photonic integrated circuits, etc.

Temperature Tunable 4D Polymeric Photonic Crystals

Isabella De Bellis et al.

Summary: This article explores tunable photonic crystals made from elastic polymers that respond to their environment, particularly with physical deformations under temperature changes. The physical structure of these crystals can be adjusted by external temperature variations, resulting in a reversible spectral tuning. By comparing the experimental results with calculations and temperature-induced shape changes, it is confirmed that the observed tuning is due to elastic deformations. The achievement of nanometric patterning of tunable anisotropic photonic materials will contribute to the development of reconfigurable photonic crystals and 4D nanostructures.

Photo-triggered full-color circularly polarized luminescence based on photonic capsules for multilevel information encryption

Siyang Lin et al.

Summary: This study demonstrates the development of device-friendly solid films with color tunability by utilizing Forster resonance energy transfer (FRET) platforms consisting of chiral donors and achiral molecular switches in liquid crystal photonic capsules (LCPCs). These LCPCs exhibit photoswitchable circularly polarized luminescence (CPL) from blue emission to RGB trichromatic signals under UV irradiation, showing strong time dependence due to different FRET efficiencies at each time node. Based on these properties, the concept of multilevel data encryption using LCPC films is demonstrated.

3D Switchable Diffractive Optical Elements Fabricated with Two-Photon Polymerization

John Sandford O'Neill et al.

Summary: Direct laser writing of multi-element diffractive optical components using two-photon polymerization is demonstrated in this study. The components can be switched on and off with an applied voltage. By utilizing the 3D capabilities of the laser microfabrication technique, multiple elements are written into a single liquid crystal layer. The switching behavior of the elements is controlled by changing the write-voltage during fabrication. These compact and transmissive optical components show great potential in applications that require switchability.

Tunable doublets: piezoelectric glass membrane lenses with an achromatic and spherical aberration control

Hitesh G. B. Gowda et al.

Summary: This article presents two versions of tunable achromatic doublets based on piezo-electrically actuated glass membranes. By controlling the actuation voltages, the chromatic focal shift and focal power can be independently adjusted. These doublets have a large aperture, short response time, and provide spherical aberration correction.
