Creating and manipulating entangled optical qubits in the frequency domain
Laurent Olislager, Erik Woodhead, Kien Phan Huy +3
Radio-frequency phase modulation of frequency entangled photons leads to a two-photon interference pattern in the frequency domain. In recent experiments, the pattern was measured…
Impact of third order dispersion on nonlinear bifurcations in optical resonators
François Leo, Stéphane Coen, Pascal Kockaert +4
It is analytically shown that symmetry breaking, in dissipative systems, affects the nature of the bifurcation at onset of instability resulting in transitions from super to subcri…
Implementing two-photon interference in the frequency domain with electro-optic phase modulators
Laurent Olislager, Ismaël Mbodji, Erik Woodhead +6
Frequency-entangled photons can be readily produced using parametric down-conversion. We have recently shown how such entanglement could be manipulated and measured using electro-o…
On-chip parametric amplification with 26.5~dB gain at telecommunication wavelengths using CMOS-compatible hydrogenated amorphous silicon waveguides
Bart Kuyken, Stéphane Clemmen, Shankar Kumar Selvaraja +6
We present the first study of parametric amplification in hydrogenated amorphous silicon waveguides. Broadband on/off amplification up to 26.5~dB at telecom wavelength is reported.…
Measuring the Nonlinear Refractive Index of Graphene using the Optical Kerr Effect Method
Evdokia Dremetsika, Bruno Dlubak, Simon-Pierre Gorza +8
By means of the ultrafast optical Kerr effect method coupled to optical heterodyne detection (OHD-OKE), we characterize the third order nonlinear response of graphene at telecom wa…
3D super-resolved in vitro multiphoton microscopy by saturation of excitation
Anh Dung Nguyen, François Duport, Arno Bouwens +6
We demonstrate a significant resolution enhancement beyond the conventional limit in multiphoton microscopy (MPM) using saturated excitation of fluorescence. Our technique achieves…
