Article Synopsis
  • - The research focuses on developing an efficient method for generating broadband, spatially separable photon pairs using a chirped quasi-phase matching (QPM) slab waveguide, which is significant for optical quantum applications.
  • - The study shows that a 3% chirped QPM slab waveguide produces a much larger photon pair bandwidth (190 nm) compared to a non-chirped version (26 nm), along with higher photon pair generation efficiency.
  • - The experiments confirmed successful two-photon interference, achieving a high visibility of 98% for the non-chirped device and 74% for the chirped device, demonstrating the effectiveness of slab waveguides in this context.

Article Synopsis
  • Quantum optical coherence tomography (QOCT) is a new method aimed at improving image resolution in optical coherence tomography (OCT), particularly when dealing with dispersion effects.
  • An experimental study successfully demonstrated QOCT's capability to achieve a depth resolution of 2.5 micrometers, the highest reported so far for this technology.
  • The results indicate that QOCT can produce clear images of dispersive materials, while traditional OCT images suffer from significant degradation.
