Reliable micro-transfer printing method for heterogeneous integration of lithium niobate and semiconductor thin films
Tom Vandekerckhove, Tom Vanackere, Jasper De Witte +6
High-speed Pockels modulation and second-order nonlinearities are key components in optical systems, but CMOS-compatible platforms like silicon and silicon nitride lack these capab…
An on-chip III-V-semiconductor-on-silicon laser frequency comb for gas-phase molecular spectroscopy in real-time
Kasper Van Gasse, Zaijun Chen, Edoardo Vicentini +7
Frequency combs, spectra of evenly-spaced narrow phase-coherent laser lines, have revolutionized precision measurements. On-chip frequency comb generators hold much promise for ful…
Second Harmonic Generation Enabled by Longitudinal Electric Field Components in Photonic Wire Waveguides
Nicolas Poulvellarie, Utsav Dave, Koen Alexander +10
We investigate type I second harmonic generation in III-V semiconductor wire waveguides aligned with a crystallographic axis. In this direction, because of the single nonzero tenso…
Physical origin of higher-order soliton fission in nanophotonic semiconductor waveguides
Charles Ciret, Simon-Pierre Gorza, Chad Husko +3
Supercontinuum generation in Kerr media has become a staple of nonlinear optics. It has been celebrated for advancing the understanding of soliton propagation as well as its many a…
On-chip optical event horizon
Charles Ciret, François Leo, Bart Kuyken +2
The interaction of waves in nonlinear Kerr waveguides are, under some circumstances, similar to the physics occurring at the horizon of black and white holes. Here, we investigate…
Coherent supercontinuum generation in a silicon photonic wire in the telecommunication wavelength range
Francois Leo, Simon-Pierre Gorza, Stephane Coen +2
We demonstrate a fully coherent supercontinuum spectrum spanning 500 nm from a silicon-on-insulator photonic wire waveguide pumped at 1575 nm wavelength. An excellent agreement wit…
An octave spanning mid-infrared frequency comb generated in a silicon nanophotonic wire waveguide
Bart Kuyken, Takuro Ideguchi, Simon Holzner +9
We demonstrate an octave-spanning frequency comb with a spectrum covering wavelengths from 1,540 nm up to 3,200 nm. The supercontinuum is generated by pumping a 1-cm long dispersio…
Dispersive wave emission and supercontinuum generation in a silicon wire waveguide pumped around the 1550 nm telecommunication wavelength
François Leo, Simon-Pierre Gorza, Jassem Safioui +5
We experimentally and numerically study dispersive wave emission, soliton fission and supercontinuum generation in a silicon wire at telecommunication wavelengths. Through dispersi…
Bridging the Mid-Infrared-to-Telecom Gap with Silicon Nanophotonic Spectral Translation
Xiaoping Liu, Bart Kuyken, Gunther Roelkens +3
Expanding far beyond traditional applications in optical interconnects at telecommunications wavelengths, the silicon nanophotonic integrated circuit platform has recently proven i…
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.…
