Evaluation of graphene optical nonlinearity with photon-pair generation in graphene-on-silicon waveguides
Yuya Yonezu, Rai Kou, Hidetaka Nishi +4
We evaluate the nonlinear coefficient of graphene-on-silicon waveguides through the coincidence measurement of photon-pairs generated via spontaneous four-wave mixing. We observed…
Generation of entangled photons using an arrayed waveguide grating
Nobuyuki Matsuda, Hidetaka Nishi, Peter Karkus +5
We propose an on-chip source of entangled photon pairs that uses an arrayed-waveguide grating (AWG) with multiple nonlinear input waveguides as correlated photon pair sources. The…
On-chip generation and demultiplexing of quantum correlated photons using a silicon-silica monolithic photonic integration platform
Nobuyuki Matsuda, Peter Karkus, Hidetaka Nishi +4
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…
A monolithically integrated polarization entangled photon pair source on a silicon chip
Nobuyuki Matsuda, Hanna Le Jeannic, Hiroshi Fukuda +6
Integrated photonic circuits are one of the most promising platforms for large-scale photonic quantum information systems due to their small physical size and stable interferometer…
