Summary: In this study, a heterojunction was constructed by bonding a single hexagonal ZnO nanorod on p-GaN through the PEDOT/HfO2 buffer, which effectively reduced optical loss and improved charge carrier injection efficiency. This resulted in UV lasing behaviors in a nano-scaled heterojunction diode, demonstrated by the narrowing of emission spectrum full width at half maximum (FWHM) from around 30 to 1.4 nm and a dramatic increase in intensity as the injection current reached 6 mA.

Summary: A modified nanostructure with a high Q-factor was proposed to achieve a nanolaser with a lower lasing threshold, supporting a hybrid plasmonic waveguide mode. The lasing action can be modulated by adjusting the thickness of the layers and the duty cycle of the grating, offering potential for designing highly-efficient miniaturized lasers.

Summary: Stable electrical modulation of plasmonic nano-lasers is achieved on a hybrid graphene-insulator-metal (GIM) platform at room temperature. A zinc oxide (ZnO) nanowire is placed on the GIM platform to create a plasmonic cavity, and the graphene layer is used for electrical modulation. The lasing thresholds of the ZnO nanowire plasmonic nanolasers on the GIM platform can be modulated by the gate voltage, demonstrating high potential for plasmonic circuit applications.

Summary: We report on the extraction of silver losses in the temperature range of 10 K-180 K using temperature-dependent micro-photoluminescence measurements and numerical simulations on silver-coated nanolasers near infrared telecommunication wavelengths. By mapping changes in the nanolaser's quality factor to silver-loss variations, we extracted the imaginary part of the silver permittivity at cryogenic temperatures and estimated the temperature-dependent values for the thermo-optic coefficient of III-V semiconductors occupying the cavity. These findings are crucial for device modeling and have practical implications for device designing and evaluating thermal effects in silver-coated nanophotonic structures.

Summary: This article demonstrates a new threshold-reduction strategy in a silver-cup plasmonic nanolaser by selectively confining plasmonic modes at the high-quality naturally cleaved surfaces at the bottom, while avoiding the rough etched surfaces of the sidewall. The nanolaser has a subwavelength volume with a record-low threshold and meets the power-consumption requirement for on-chip optical interconnects in photonic integrated circuits.

Summary: Heterostructures formed by 2D TMDCs and graphene are important for exploring interface physics and optoelectronic devices. This study successfully disentangled the effects of light-induced charge transfer, heating, and strain in WS2/graphene heterostructure. The results show that without separating these effects, the estimation of carrier density may have significant errors, and this approach provides a way for understanding the properties of heterostructures comprehensively.
