Three-dimensional (3D) plasmonic sensors have been developed using the reversal nanoimprint technology. Using this technology, plasmonic sensors with additional levels of metals and asymmetrical profiles were optimized to achieve high sensitivity for biomolecule detection. Combining the unique designs of these 3D nanostructures, the plasmonic sensors have high performance as the devices combined the hybrid coupling effect of localized surface plasmon resonance, Fano resonance, and Fabry-Perot cavity modes to achieve sharp resonance peaks with large resonance peak shifts. Applications of these high performance nanoplasmonic sensors to biosensing will be presented.

A new scheme of advanced driving beam (ADB) module employing ultra-reliable Ce: YAG-based single crystal phosphor (SCP) for use in autonomous vehicles is demonstrated. The Ce: YAG-based SCP layers fabricated by high-temperature of 1500°C exhibits excellent thermal stability. The ADB module consists of a Nichia blue LED with silicone-based phosphor, a digit mirror device (DMD), a projection lens, and two Nichia laser diodes with a Ce: YAG-based SCP layer. The ADB pattern is measured to be 88,436 luminous intensity at 0°, 69,393 cd at ± 2.5°, and 42,942 cd at ± 5°, which are well satisfied the ECE R112 class B regulation. The proposed high-performance ADB module with ultra-reliable Ce: YAG-based SCP layer is favorable as one of the promising ADB module candidates for use in the next-generation automobile headlight applications.

Phase retrieval is the key technique in phase-modulated holographic storage. In this paper, a deep convolutional neural network is proposed to directly retrieve phase data. Compared with the traditional non-interferometric phase retrieval method, this method has the advantages of fast retrieval speed and high reconstruction accuracy. In this paper, the influence of intensity image noise on retrieval results under different retrieved conditions is researched and analyzed. By establishing a simulation system that is in strict agreement with real experiments, the lensless spatial diffraction images are generated. By adding different proportions of random noise into the intensity images we get the training dataset. The convolutional neural network is trained by a training dataset and tested by a new noisy test dataset. Experimental results show that the phase retrieval method based on deep learning has a high tolerance for systematic errors and strong anti-noise performance.

Based on polarization holography theory, the plane bifocal vector lens is studied. In previous studies, the bifocal vector lens were limited to cross-angle π/2 and bulk materials. However, when the two waves are orthogonal circularly polarized state, the plane bifocal vector lens can be realized, and the limitation of cross-angle π/2 and bulk materials can be broken. The lens produces corresponding focus output through the reading wave with different polarization states, which can be used for large-area optical element research.

Nanoscale optical writing enables high-density optical data storage. However, current techniques usually require high laser beam intensity with high energy consumption and short device lifetime. Upconversion nanoparticles (UCNPs) have shown great potential for high-density optical data storage due to their exceptional luminescence emissions. In addition, UCNPs have enabled low-power STED microscopy. We show that UCNPs can induce the reduction of graphene oxide (GO) at the nanoscale. Dual-beam super-resolution irradiation was used to write features in UCNP-conjugated GO with lateral feature size at the nanoscale and inhibition intensity of <15 MW/cm^2. This approach might offers a convenient and energy-efficient solution for the storage demands in the Data Age.
