Structural color materials with reversible stimuli‐responsiveness to external environment have been widely used in sensors, encryption, display, and other fields. Compared with other stimuli, visible light is highly controllable both temporally and spatially with less damage to materials, which is more suitable for structural color patterning. Herein, a new diselenide‐containing shape memory material is prepared and used for creating patterns via visible light stimulus. In this system, the structural color originates from birefringence of stretched materials, whose shapes can be fixed while maintaining the mechanical stress. The fixed stress can be released by diselenide metathesis under visible light irradiation. By regulating the wavelength or irradiation time with a commercial projector, the pattern with tunable structural colors is realized and the structural color pattern can be erased and rewritten arbitrarily. During the patterning process, the optical signal is first stored as mechanical signal and then transformed back to optical signal. It is a new method for preparing visible‐light‐responsive structural color material and has great potential in display devices, anticounterfeiting labels, and data storage.

Co-extruded multilayer films for high capacity optical data storage

New approaches for optical data storage (ODS) applications are needed to meet the future requirements of applications in multimedia, archiving, security, and many others. Commercial data storage technologies are moving to threedimensional (3D) materials, but the capacity is limited by the fabrication cost and the number of layers that can be addressed using the reflection-based storage mechanism. We demonstrate here storage systems based on co-extrusion of multilayer (ML) films that can overcome these problems. The organic roll-to-roll films produced can easily be produced hundreds of meters in length, in a far simpler and cheaper manner than current manufacturing methods such as spin coating and lamination. The medium consists of alternating active and buffer layers, and data storage is demonstrated by writing images in 23 layers of 78 µm thick films by fluorescence (FL) quenching of an organic dye. The areal data resolution is at the diffraction limit of the CW Blu-ray (BR) laser employed, and the co-extrusion technique allows for small layer spacings, leading to a total bit density 1.2 Tb/cm 3 . We anticipate materials already demonstrated successful for 3D ODS will be adapted to this technique, as well as new systems developed, to take full advantage of this medium.

“…1 2 Optical storage devices offer significant advantages over other high-capacity storage devices, such as tape and microfilm, 3 with faster access times and a hierarchical-type file organisation. [4][5][6] A number of research works have investigated the soliton pulses in several areas such as in physics, 7 optical soliton communication, 8 especially, in optical quantum telecommunication.

Optical system of microring resonator is presented to form the femtosecond (fs) memory time of optical soliton signals. Localised soliton pulses can be stored within the microring device using suitable parameters of the system. The optical quantum memory is a solution for storing large amounts of data which is very inexpensive and more importantly, it helps to transport the data between optical communication devices. The integrated optical system of a series of microring resonators and two add or drop systems are presented. This system is used to generate chaotic signals using an input bright soliton pulse. The large output gain is obtained by the self-phase modulation which is required to balance the dispersion effects of the medium. The ultra-short single and multi-spatial and temporal soliton pulses are obtained by using the add/drop filter systems. The results show that the single and multi-soliton pulses can be localised within the microring waveguide while the optical quantum memory time of 83 fs could be generated.
