Overview

Randomized trial demonstrates integration of quantum light source in hBN via stable waveguides, suggesting improved photonic circuit reliability.

Key Points

  • This research aims to enhance the integration of quantum light sources with photonic circuits using ultra-stable waveguides.
  • Fabrication of ultra-stable optical waveguides using ultrafast laser direct writing within glass.
  • Creation of emissive defects in hBN using single pulse ultrafast laser irradiation followed by high-temperature annealing at 950 °C.
  • Development of a waveguide/hBN butt-coupling integrated device to facilitate efficient light emission.
  • Ultra-stable waveguides can withstand high temperatures up to 1100 °C, enhancing integration potential for hBN emitters.
  • Efficient defect emissions in the integrated hBN were achieved, enabling strong coupling and light propagation through the waveguide.
