Entanglement without indistinguishability: Routing of coupling-induced path-entangled photon pairs
Raja Ahmad, Ayman F. Abouraddy
Realizing an on-chip reconfigurable source of path-entangled photons is of critical importance for the advancement of quantum information processing and networking. Achieving this…
Wavelength conversion of data at gigabit rates via nonlinear optics in an integrated micro-ring resonator
Alessia Pasquazi, Raja Ahmad, Martin Rochette +5
We present the first system penalty measurements for all-optical wavelength conversion in an integrated ring resonator. We achieve wavelength conversion over a range of 27.7nm in t…
Power-efficient production of photon pairs in a tapered chalcogenide microwire
Evan Meyer-Scott, Audrey Dot, Raja Ahmad +3
Using tapered fibers of As2Se3 chalcogenide glass, we produce photon pairs at telecommunication wavelengths with low pump powers. We found maximum coincidences-to-accidentals ratio…
Converting one photon into two via four-wave mixing in optical fibers
Audrey Dot, Evan Meyer-Scott, Raja Ahmad +2
Observing nonlinear optical quantum effects or implementing quantum information protocols using nonlinear optics requires moving to ever-smaller input light intensities. However, l…
Far detuned mid-infrared frequency conversion via normal dispersion modulation instability in chalcogenide microwire
Thomas Godin, Yves Combes, Raja Ahmad +3
We report the observation of modulation instability in the mid-infrared spectral region by pumping a hybrid polymer-chalcogenide optical microwire with a femtosecond optical parame…
All chalcogenide Raman parametric Laser, Wavelength Converter and Amplifier in a Single Microwire
Raja Ahmad, Martin Rochette
Compact, power efficient and fiber compatible lasers, wavelength converters and amplifiers are vital ingredients for the future fiber optic systems and networks. Nonlinear optical…
