  Antireflective vertical-cavity surface-emitting laser for LiDAR

  The authors showcase an innovative anti-reflective vertical-cavity surface-emitting laser (AR-VCSEL) that achieves low divergence and maintains a single-mode lasing. The 6-junction AR-VCSEL array demonstrates low divergence from 8° to 16° (D86) and tripled brightness compared to conventional counterparts. The AR-VCSEL offers an excellent avenue for long-distance LiDARs.

  Long operating lifetime mid-infrared LEDs based on black phosphorus

  Mid-infrared light emitting diodes (LEDs) based on black phosphorus (BP) have shown promising performance, but they are usually limited by the environmental instability of the material. Here, the authors extrapolate a room-temperature operational lifetime of BP LEDs up to ~ 15,000 h via Al₂O₃ passivation and nitrogen seal packaging.

  Low-noise frequency-agile photonic integrated lasers for coherent ranging

  Stable and tunable integrated lasers are fundamental building blocks for applications from spectroscopy to imaging and communication. Here the authors present a narrow linewidth hybrid photonic integrated laser with low frequency noise and fast linear wavelength tuning. They then provide an efficient FMCW LIDAR demonstration.

  Dynamics of soliton self-injection locking in optical microresonators

  Self-injection locking of the pump laser for a soliton microcomb has significantly relaxed the requirements for laser drives. Here the authors study self-injection locking in experiment and theory and reveal that the soliton formation is feasible with detunings unreachable according to previous theories.

  Hybrid perovskite light emitting diodes under intense electrical excitation

  Hybrid perovskite semiconductors are promising for wavelength-tunable laser diodes but their behavior under intense electrical excitation remains unexplored. Kim et al. investigate perovskite light emitting diodes at current densities nearing 1 kA cm⁻² and suggest that a laser diode is within reach.

  Operating organic light-emitting diodes imaged by super-resolution spectroscopy

  There is a need to characterize devices during operation in real-time and at nanoscopic length scales. Here, King et al. perform electroluminescence-STED imaging with a polymer based light-emitting diode, revealing nanoscopic defects that would be unresolvable with traditional optical microscopy.

  Synergetic electrode architecture for efficient graphene-based flexible organic light-emitting diodes

  Replacing indium tin oxide with graphene in organic light-emitting diodes is a promising approach to enhance the flexibility of displays and light sources. Here, the authors combine graphene, TiO₂and low-index hole-injection layers to achieve high external quantum efficiency and good bendability.

  Active graphene–silicon hybrid diode for terahertz waves

  Graphene has demonstrated the ability to modulate terahertz (THz) waves by optical or electrical excitation, but modulation depths have been low. Here, Li et al. demonstrate enhanced modulation and polarity-dependent THz attenuation using external voltage bias and photoexcitation on a graphene–silicon film.
