Here, we develop a coupler-free microlaser platform that integrates resonance energy transfer (RET) with whispering-gallery-mode (WGM) lasing to transduce hybridization-dependent RET into gain-competition-mediated lasing-mode switching. In this system, RET encompasses short-range non-radiative Förster resonance energy transfer (FRET) between surface-proximal donor–acceptor pairs and cavity-mediated radiative energy transfer through resonant WGM photons. Using DNA-grafted microspheres as laser probes, the system enables low-threshold lasing under free-space pumping. Hybridization-induced acceptor recruitment progressively redistributes the donor–acceptor gain balance, inducing discrete switching between adjacent WGM resonances with a characteristic spacing of Δλ = 3.97 nm that serves as a built-in spectral ruler.

Conventional neuromorphic devices, though promising for brain-inspired computing, suffer from severe degradation in aqueous environments, limiting their application in underwater scenarios. Here, we develop a water-resistant optoelectronic synapse based on a Rubrene/FA₃Bi₂I₉/ZnO heterojunction, where the hydrophobic Rubrene layer effectively suppresses water infiltration, preserving the microstructure and optoelectronic performance of the lead-free perovskite even after prolonged water immersion. The device exhibits various synaptic plasticities and can achieve controllable transitions from short-term memory to long-term memory by adjusting the parameters of the light pulses. Due to its excellent multi-spectral response characteristics, we demonstrate the ability to filter redundant information and extract target features in complex light environments. Moreover, a 5 × 5 pixel array exhibits signal‑to‑noise separation, while a 256 × 144 resolution input frames integrated with a fully connected neural network achieves high‑precision classification of aquatic organism movement trajectories with 95.89% accuracy.

Vortex beams carrying orbital angular momentum (OAM) have helical phase fronts and are useful for high-speed optical communication, microscopic particle manipulation, and high-capacity information encoding. Direct generation of tunable vortex beams on an SP radiation platform therefore provides an attractive pathway for multifunctional integrated photonic devices. However, existing approaches based on conventional gratings or single-function metasurfaces often suffer from low radiation intensity and difficulty in simultaneously achieving radiation enhancement, polarization control, and high-quality vortex beam generation. Here, we propose and numerically validate a double-layer C-ring metasurface for compact terahertz vortex beam generation. Radiation enhancement is achieved through electric-field-strength superposition between the radiation generated by Layer I and the field contribution excited in Layer II by the electron-induced evanescent field. The second layer further combines dynamic and geometric phase modulation to generate vortex beams with controlled OAM. The generation of vortex beams under different polarization states is also verified, indicating that the design is robust against variations in polarization excitation.

However, traditional polarization detection schemes typically rely on bulky mechanical rotating elements or complex multi-device cascading, which inevitably limits system response speed, footprint, and power efficiency. To address these limitations, this study demonstrates a compact single-pixel polarization detector based on a black phosphorus/molybdenum disulfide (BP/MoS₂) van der Waals heterojunction. By precisely manipulating the interfacial energy-band engineering, the device achieves unique bipolar photoresponse characteristics in a low-power mode near zero bias (±0.01 V). Without the need for mechanical rotating parts or detector arrays, the device enables the decoupled detection of incident polarization and intensity by leveraging the inherent competition between built-in and external electric fields. Furthermore, we propose a novel elliptical fitting algorithm based on the two-dimensional mapping of photocurrents, successfully extracting the polarization angle and light intensity synchronously within a single detection unit.
