Summary: This paper proposes an evolutionary single-pixel imaging (SPI) scheme for solving combinational optimization problems. SPI is a unique optical imaging technique that replaces the pixelated sensor array with a single-pixel detector. In this study, SPI is used to process types of data other than images, such as number partition and graph maximum cut. The Ising machine model is implemented optically with SPI, where the illumination patterns are updated through selection, crossover, and mutation based on the feedback of single-pixel values.

Summary: We demonstrate photon-counting single-pixel imaging in the ultraviolet region using a 4H-SiC single-photon avalanche diode (SPAD) as a high-performance compact single-photon detector. By developing a tailored readout circuit with active hold-off time, we restrain detector noise and operate the SPAD in the free-running mode. With structured illumination, we reconstruct compressed images at a 4 fps frame rate, demonstrating the capability of ultraviolet imaging applications.

Summary: This paper investigates two types of single-pixel imaging systems for performing optical logic gate operations. The first scheme encodes the spatial light intensity distribution of the object image and illumination pattern based on input binary values, and the logic gate output result is indicated by the maximum single-pixel intensity. In the second scheme, the light amplitudes in corresponding sub-regions are directly proportional to the binary input values, and a universal linear approximation model allows the detected light intensity of a single-pixel holography system to represent the logic gate output result.

Summary: Single-pixel imaging (SPI) is a novel imaging modality that captures images using a single-pixel detector and time-varying modulation patterns. A new model-driven SPI reconstruction method, based on an untrained convolutional autoencoder network (UCAN), is proposed. This method does not require pre-training and produces high-quality reconstructions. Simulations and real-world experiments demonstrate the superiority of the proposed method over existing algorithms in SPI.

Summary: In this article, a transmitter design for underwater wireless optical communication (UWOC) systems based on a single-color LED array and a beam shaping system is introduced. The lens group-based beam shaping scheme extends the transmission distance and maintains the easy-alignment nature and stability of the LED-based UWOC link. At the receiver, a diversity reception scheme with an array of PMTs and a high-gain scheme combining a PMT with an optical antenna are adopted. Hardware pre-equalization and nonlinear post-equalization techniques are used to reduce inter-symbol interference and compensate for signal distortion. The proposed UWOC system with relaxed alignment requirement is tested in laboratory, swimming pool, and real sea environments to verify its stability and practicability.

Summary: This article investigates the dynamic modulation of optical skyrmions by changing the field symmetry and adding chirality. The study reveals that field symmetry controls the transformation between skyrmions and merons, while material chirality regulates the degree of twist in the fields and spins, and governs the skyrmionic transition. The enantioselective twist of skyrmions and merons arises from the chirality-induced splitting of the hyperboloid in momentum space. The research enriches the portfolio of optical quasiparticles and deepens our understanding of light-matter interaction, paving the way for applications such as chiral sensing, optical tweezing, and topological phase transitions in quantum matter.

Summary: In this paper, a nonlocal optical information-processing system called ghost diffractive deep neural networks (GD2NNs) is proposed, which combines traditional ghost diffraction with cascaded diffraction layers learned with use of diffractive deep neural networks. The system uses light's second-order coherence to enable image-free and interferometer-free coherent beam-demanded phase-object sorting with thermal light. Furthermore, GD2NNs convert the general encoder-decoder-detector cascaded framework into a parallel one, resulting in no optical interaction between the encoder and the decoder.
