Query: On-chip generation and demultiplexing of quantum correlated photons
  using a silicon-silica monolithic photonic integration platform   We demonstrate the generation and demultiplexing of quantum correlated
photons on a monolithic photonic chip composed of silicon and silica-based
waveguides. Photon pairs generated in a nonlinear silicon waveguide are
successfully separated into two optical channels of an arrayed-waveguide
grating fabricated on a silica-based waveguide platform.
